The invention provides an image forming apparatus including an image bearing member, a transfer member for transferring a toner image from the image bearing member, and a first contact portion and a second contact portion which can be mutually contacted for applying a voltage to the transfer member, the first contact portion having a convex portion, wherein the transfer member is pressed toward the image bearing member by a pressure exerted between the first contact portion and the second contact portion, and the convex portion has a hardness larger than that of the second contact portion. It is rendered possible to prevent an intrusion of toner or the like into the electrical contact portion, thus resulting in a contact failure.
