In a sheet feeding apparatus, a member, supporting at one end thereof a rotatable pressure roller, is mounted turnably at the other end thereof on an input shaft driven by a motor. This member is coupled to the input shaft via a friction generating mechanism which generates a friction force. This friction force allows the rotatable pressure roller to be pressed with an optimum pressure onto a sheet to be fed.

Sheet feeding apparatus with a constant friction torque generating

An electrophotographic copier has a photoconductive apparatus including a photoconductive belt and at least first and second rollers around which the photoconductive belt runs, a first body, a development apparatus mounted on the first body and having a support for positioning and supporting the first roller at both ends thereof, and the first body having a single fixing device thereon at a point spaced from the first roller, a second body, and an optical apparatus mounted on the second body, the second body supporting the photoconductive apparatus and having a guide for determining the positions of the first and second rollers, the second body being supported by the single fixing device, whereby the second body is supported substantially at three points on the first body.
