Abstract:
1. An image forming apparatus, comprising: a charge unit configured to charge a surface of an organic photo conductor (OPC) to a predetermined electric potential during a charging operation; a developing unit configured to develop an electrostatic latent image formed on the surface of the OPC by applying developer on the electrostatic latent image during a developing operation; a power supply unit configured to supply voltages to the charge unit and the developing unit; and a control unit configured to control the voltages supplied to the charge unit and the developing unit, such that during a non image forming operation in which no image is formed, the control unit is configured to control the power supply unit to cause at least one of the charge unit and the developing unit to be supplied with a voltage that is different from a normal charge voltage that is supplied to the charge unit during the charging operation and from a normal developing voltage that is supplied to the developing unit during the developing operation, such that an absolute value of the voltage that is different from the normal charge voltage is larger than that of the normal charge voltage.
