Abstract

PURPOSE: To improve the copying speed at the time of small sizes by selectively controlling the number of revolutions of a photosensitive drum to obtain one sheet of copy according to the magnitude of copying material sizes.
CONSTITUTION: When the original passes on the galss plate 23 of a lighting part 22, it is radiated by a lamp 24. In an exposure part 27, exposure to the photoreceptor on the photosensitive drum 17 surface is accomplished, by which electrostatic latent images are formed. After the images are developed with a developing device 32, they are transferred onto the transfer paper P being sent from a transfer paper cassette 6 and are dried and fixed in a drying and fixing part 41. In this case, the transfer paper size is discriminated by the signal from the cassette 6 and the kind of the original is discriminated by changinig the position of the original platen. This results in that when the transfer paper P is of an A3 size, two sheets of the originals of an A4 size are fed and two sheets of copying are done during on rotation of the drum 17.
