Description
本発明は、消耗品パックおよび消耗品パックの製造方法に関する。 The present invention relates to a consumable pack and a method for manufacturing a consumable pack.
例えば電子写真方式を用いた複写機、プリンタ等の画像形成装置では、ドラム状に形成された像保持体の表面を帯電し、この像保持体の表面を画像情報に基づいて制御された光で露光して像保持体の表面上に静電荷像（静電潜像）を形成し、この静電荷像を静電荷像現像用トナーや静電荷像現像用キャリアを含む静電荷像現像用現像剤により現像してトナー画像とし、さらにこのトナー画像を記録紙等の被転写材に転写し、これを定着装置によって定着して画像を形成する。 For example, in an image forming apparatus such as a copying machine or a printer using an electrophotographic system, the surface of an image carrier formed in a drum shape is charged, and the surface of the image carrier is controlled by light controlled based on image information. An electrostatic image (electrostatic latent image) is formed on the surface of the image carrier by exposure, and the electrostatic image is developed with an electrostatic charge image developing toner or an electrostatic charge image developing carrier. The toner image is developed into a toner image, and the toner image is further transferred onto a transfer material such as a recording paper and fixed by a fixing device to form an image.
この電子写真方式の画像形成装置に用いられる、トナー、キャリア、これらを含む現像剤、像保持体としての感光体、定着装置等の消耗品、あるいはそれら消耗品を含むカートリッジ等のユニットを構成する材料から揮発性有機化合物（ＶＯＣ）等の揮発成分が発生することがある。この揮発成分の発生を低減するために、吸着剤をトナー内に添加する、吸着剤をトナーカートリッジ内に添加する、トナーを密封するフィルムシールの内側に吸着層を設けるといった技術が提案されている。 A unit such as a toner, a carrier, a developer containing them, a photosensitive member as an image holding member, a consumable item such as a fixing device, or a cartridge containing these consumable items, used in the electrophotographic image forming apparatus. Volatile components such as volatile organic compounds (VOC) may be generated from the material. In order to reduce the generation of this volatile component, techniques such as adding an adsorbent into the toner, adding an adsorbent into the toner cartridge, and providing an adsorbing layer inside the film seal that seals the toner have been proposed. .
例えば、トナーを収納し、画像形成装置にトナーを補給するトナー補給容器において、トナー補給開口部を有するトナー容器と、トナー補給開口部を密封そして開封し得るシール部材と、を有するとともに、シール部材がトナー等から発生する揮発性有機化合物を吸着する吸着性を有しているトナー補給容器が開示されている（例えば特許文献１参照）。 For example, in a toner supply container for storing toner and supplying toner to the image forming apparatus, the toner container includes a toner container having a toner supply opening, and a seal member capable of sealing and opening the toner supply opening. Discloses a toner replenishing container having an adsorptivity for adsorbing a volatile organic compound generated from toner or the like (see, for example, Patent Document 1).
また、画像形成装置に用いられる消耗品を、内側からガス透過性が高い第１包装材料とガス透過性が低い第２包装材料の順で包装し、第１包装材料と第２包装材料との間に吸着剤を挿入した包装体が提案されている（例えば特許文献２参照）。 Further, the consumables used in the image forming apparatus are packaged from the inside in the order of the first packaging material having a high gas permeability and the second packaging material having a low gas permeability, and the first packaging material and the second packaging material. A package with an adsorbent inserted between has been proposed (see, for example, Patent Document 2).
また、トナーや現像剤を、透湿性が０．７（ｇ／ｍ２／日）以下の包装材料により包装する方法が提案されている（例えば特許文献３，４参照）。 In addition, a method has been proposed in which toner and developer are packaged with a packaging material having a moisture permeability of 0.7 (g / m 2 / day) or less (see, for example, Patent Documents 3 and 4).

以下、本発明の実施形態について詳細に説明する。 Hereinafter, embodiments of the present invention will be described in detail.
＜消耗品パック＞
本実施形態に係る消耗品パックは、通気度が５０ｓ／ｍｌ以上３０００ｓ／ｍｌ以下である包装材と、該包装材により包装された画像形成装置用の消耗品と、を有する。
<Consumables pack>
The consumable pack according to the present embodiment includes a packaging material having an air permeability of 50 s / ml or more and 3000 s / ml or less and a consumable for an image forming apparatus packaged with the packaging material.
画像形成装置用消耗品においては、揮発性有機溶剤が原材料に含まれたり、揮発性有機溶剤が生産工程に使用されることにより消耗品の中に該揮発性有機溶剤が残存することがあり、これら揮発性有機溶剤の残存量の低減が求められている。特に静電荷像現像用トナーおよび静電荷像現像用キャリア中の揮発性有機溶剤を、減率乾燥領域で除去するには長期の乾燥時間を有し、更に乾燥工程中に攪拌などを実施すると粒子表面の劣化が進むことがある。また、透湿性の低い包装材で包装した消耗品パックを高温多湿環境において開封し画像形成装置に設置した場合、消耗品、特に静電荷像現像用トナーや静電荷像現像用キャリアが急激に吸湿することにより帯電性に変動が生じ、初期印字濃度の変動が発生する。 In the consumables for image forming apparatuses, the volatile organic solvent may be contained in the raw material, or the volatile organic solvent may remain in the consumables when the volatile organic solvent is used in the production process. Reduction of the residual amount of these volatile organic solvents is demanded. In particular, the volatile organic solvent in the toner for developing an electrostatic charge image and the carrier for developing an electrostatic charge image has a long drying time for removing it in the reduced rate drying region, and further, when stirring or the like is performed during the drying process, the particles Surface degradation may progress. In addition, if a consumable pack packed with a packaging material with low moisture permeability is opened in a high-temperature and high-humidity environment and installed in an image forming apparatus, the expendables, especially the toner for developing electrostatic images and the carrier for developing electrostatic images, absorb moisture rapidly. As a result, the chargeability fluctuates and the initial print density fluctuates.
これに対し、本実施形態に係る消耗品パックは、通気度が上記範囲である包装材によって画像形成装置用消耗品が包装されているため、使用される環境で包装材内部の消耗品が保管され、該消耗品を実際に使用する際においても品質が安定するまでの時間が短縮されるものと推測される。また、通気度が上記範囲である包装材によって消耗品が包装されているため、包装後保管する状態で残存溶剤が低減されるものと推測される。更に、消耗品を包装した後に乾燥工程を設けて乾燥を施し得るものと推測される。 In contrast, in the consumable pack according to the present embodiment, the consumable for the image forming apparatus is packaged with the packaging material whose air permeability is in the above range. Therefore, it is estimated that the time until the quality is stabilized is shortened even when the consumable is actually used. In addition, since the consumables are packaged by the packaging material having the air permeability in the above range, it is estimated that the residual solvent is reduced in a state of being stored after packaging. Further, it is presumed that after the consumables are packaged, a drying step can be provided for drying.
尚、本明細書において「包装」とは、通気度が上記範囲である包装材を透過する気体以外には、包装されたパックの内側に気体が入らないよう隙間なく密閉された状態を指す。 In the present specification, “packaging” refers to a state of being sealed without a gap so that gas does not enter the inside of the packaged pack other than the gas that permeates the packaging material having an air permeability within the above range.
本実施形態に係る消耗品パックは包装材の通気度が上記範囲であり、更には２００ｓ／ｍｌ以上２０００ｓ／ｍｌ以下がより好ましく、５００ｓ／ｍｌ以上１５００ｓ／ｍｌ以下が特に好ましい。
通気度が５０ｓ／ｍｌ以上であることにより、空気が急激に出入りすることが無く、保管環境の急激な温度変化においても画像形成装置用消耗品が結露しにくい。３０００ｓ／ｍｌ以下であることにより、揮発性有機溶剤が長時間かけることなく除去され、かつ保管環境に適時に変化する。
In the consumable pack according to this embodiment, the air permeability of the packaging material is in the above range, more preferably 200 s / ml to 2000 s / ml, and particularly preferably 500 s / ml to 1500 s / ml.
When the air permeability is 50 s / ml or more, air does not enter and exit abruptly, and the consumables for the image forming apparatus are unlikely to condense even in a rapid temperature change in the storage environment. By being 3000 s / ml or less, the volatile organic solvent is removed without taking a long time, and changes to the storage environment in a timely manner.
尚、通気度はＪＩＳ Ｐ ８１１７（２００９年）の方法でガーレー試験機を使用して測定される。本明細書に記載の数値は、該方法によって測定されたものである。 The air permeability is measured using a Gurley tester by the method of JIS P 8117 (2009). The numerical values described in this specification are measured by the method.
