Abstract
The copying apparatus has a magnification ratio varying device, and a photosensitive member, in motion, is exposed to an optical image of an original, by slit exposing, to form an electrostatic latent image thereon. The scanning velocity of the original is effected in accordance with the selected magnification ratio. Registration of the forward or leading end of the image of an original with the leading end of a photosensitive sheet or a transfer-printing sheet is effected by delivering a copy sheet, such as a photosensitive sheet or a transfer-printing sheet, to the photosensitive member only after the lapse of a predetermined period of time following production of a detection signal by a detection device cooperable with the leading edge of the original. The predetermined period of time is varied in conformity to the selected magnification ratio.
