An image forming apparatus includes a first conductive member, a photoelectric transfer layer mounted on the first conductive member, a surface electrode mounted adjacent to the photoelectric transfer layer but away from the first conductive layer, a dielectric layer opposed to the surface electrode, a second conductive member mounted on one surface of the dielectric layer away from the photoelectric transfer layer. A first power supply is provided for applying a voltage Vc between first and second conductive members and a second power supply is provided for applying a voltage Vb between the surface electrode and the second conductive member. The image forming apparatus satisfies following relationship: Vb>(5.5)Vc-(1+5.5/Dp)(312+6.2Da) wherein Vb: Voltage between surface electrode and second conductive member; Vc: Voltage between first and second conductive members; Dp: Thickness of photoelectric transfer layer; and Da: Distance between dielectric layer and photoelectric transfer layer.
