As is apparent from the above description, the present invention is a facsimile communication method for transmitting and receiving an image signal using a facsimile apparatus having a transmitting section, and the receiving side apparatus is set to its own facsimile apparatus. The size of the recording paper is detected, it is determined whether or not it is equal to or larger than a predetermined size, and a signal indicating the result of the determination is sent to the transmission side device, and at the transmission side device, the signal sent from the reception side device. If it is determined that the size is less than the predetermined size, whether to reduce the size is determined based on the size of the transmission original and the size of the recording paper on the receiving side, and if it is determined that the size is equal to or larger than the predetermined size, the original is transmitted in the original size. By doing so,
Since the image signal is reduced in the sending device according to the recording paper size of the receiving device, the image signal should be received and recorded even when the recording paper size of the receiving device is smaller than the size of the transmitted document. You can Furthermore, when the device on the receiving side sends a signal indicating that the size is equal to or larger than the predetermined size, the sending original is sent out in full size without comparing the sizes of the original and the recording paper.
