ABSTRACT:
An electrostatic copying apparatus comprises a photosensitive body forming a toner image on the surface thereof, and a transfer device for transferring electrostatically the toner image formed on the surface of the drum to a copying paper. The transfer device includes a rotatable transfer roller which faces the surface of the photosensitive drum for selectively transferring at least two different sizes of the copying paper. The transfer device comprises a moving mechanism for driving the transfer roller for such a period as to feed the copying paper for a distance equal to the length thereof in the feeding direction, while keeping the copying paper in contact with the photosensitive drum. Additionally, apparatus is provided for forming a toner image on the surface of the drum corresponding in width to that of the copying paper being utilized.
