A transfer flow-in current which flows from a transferring device into an image carrier, a separation flow-in current which flows from a separating device into the image carrier, an aperture width in the recording member transporting direction of an aperture of the transferring device, and an aperture width in the recording member transporting direction of an aperture of the separating device are set so as to have the relationship: separation flow-in current&equals;transfer flow-in current&times;(transfer aperture width/separation aperture width).

Electrophotographic apparatus including transferring device

A transfer guide is provided which includes a guide member for guiding paper to a transfer point and a paper holding member using an electrically conductive member attached to the guide member by means of a spring member and disposed in the vicinity of a surface of a photosensitive drum, such that the gap becomes narrow for thin paper and the gap widens for thick paper in correspondence with the ream weight of the paper.
