Abstract
A transfer sheet separating/conveying member is formed of an electrically conductive material, and has its part disposed close to or in contact with the peripheral surface of a photosensitive drum for movement in the same direction as the drum. The separating/conveying member is applied with a voltage of the same polarity as that of a voltage applied to the transfer sheet. An insulating material covers at least a portion of the laterally opposite sides of the separating/conveying member which are located opposite to the drum surface. A corner of the separating/conveying member which is not covered by the insulating material and remains exposed is shaped into a rounded form.
