ABSTRACT:
A transfer roller which transfers a toner image to a recording sheet fed in a gap between a photoreceptor drum and the transfer roller, and a pre-transfer guide which guides the recording sheet are pushed to be displaceable by a spring by use of a roller so that a predetermined gap is maintained between the photoreceptor drum and the transfer roller and that the positions of the transfer roller and the pre-transfer guide depend on the position of the photoreceptor drum. The recording sheet P on which an image has been transferred is conveyed to a conveying guide. A post-transfer guide which receives the abutment of the end of the image transferred recording sheet and guides the recording sheet to the conveying guide is provided to be displaceable integrally with the transfer roller and the pre-transfer guide. The post-transfer guide is made of a resin with a resistance of 10.sup.10 .OMEGA. to 10.sup.16 .OMEGA..
