A large amount of digital memory is used to process digital information of an image obtained by scanning an original, convert the signal into, for example, a light beam and convert it to a photosensitive member. A so-called digital copying apparatus on which an electrostatic latent image is formed has been put to practical use. That is, an original is read by a scanner unit using an image sensor such as a CCD, converted into digital image data, stored in an image memory (semiconductor memory), and a printer unit such as a laser beam printer (polygon mirror). , Composed of a semiconductor laser, an image forming optical system, etc.).

Further, since the image data stored in the image memory can be repeatedly read, the copying operation can be performed at a high speed without repeatedly reading the original by the scanner unit to obtain a plurality of copies. . Also, if an error such as a paper jam occurs in the printer unit, it is not necessary to read the original again in the scanner unit.
Recovery processing is simplified. Furthermore, when copying a plurality of documents using an automatic document feeder or the like, it is possible to handle the documents without worrying about errors in the printer unit, thereby simplifying the control and operation of the device.
