An image forming apparatus includes an electrophotographic photosensitive member; a charger for charging the photosensitive member to form an electrostatic latent image on the photosensitive member; an exposure device for exposing the photosensitive member to image light; a developing device for developing the latent image with toner; a transfer member contactable to the photosensitive member at a transfer position, the transfer member comprising an electrically conductive base, a high resistance surface layer, and a low resistance or intermediate resistance conductive layer between the conductive base and the surface layer; and transfer voltage applying device for applying a transfer voltage to the transfer member; wherein Ws>Wt>Wp>W1 is satisfied, where Ws is a width of a photosensitive layer measured in a direction perpendicular to a movement direction of the photosensitive member, W1 is an image exposure width of the exposure device, Wp is a width of a transfer material usable with the image forming apparatus, and Wt is an overlapping width between a charging width of the charger and the width of the conductive layer of the transfer member.
