Abstract
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.
