ABSTRACT:
An electrophotographic apparatus which includes a rotating photosensitive drum on which an electrostatic charge latent image is formed; a developing device for developing the latent image with toners to form a toner image on the drum; a transfer roller for transferring the toner image onto a record paper and arranged movably with respect to the drum; and a record paper detector for detecting a paper jamming to produce a paper jam signal. The rotation of the drum is stopped and the transfer roller is moved away from the photosensitive drum in response to the paper jam signal so as to make it easy to remove the jammed paper, and the transfer roller is moved into an initial operative position after the ddrum has rotated by such an angle that residual toners and electrostatic charge on the drum pass through the transfer roller.
