Abstract:
An image forming apparatus includes a detection unit (control unit) configured to detect operation information of the image forming apparatus and a controller (control unit) configured to apply an AC voltage to a charging roller by a charging power source during a non-image-forming operation of the image forming apparatus. The controller is configured to control the duration for which the AC voltage is applied on the basis of the operation information detected by the detection unit.

Claim (Index 1):
An image forming apparatus configured to carry out an image forming operation of forming an image on a recording material, the image forming apparatus comprising:\n an image bearing member configured to be rotatable; a charging member configured to charge the image bearing member; a voltage application device configured to apply a voltage to the charging member; an image exposure device configured to form an electrostatic latent image on the image bearing member charged by the charging member; a developing device configured to supply developer to the electrostatic latent image formed on the image bearing member by the image exposure device so as to develop the electrostatic latent image into a toner image; a transfer member configured to transfer the toner image formed on the image bearing member by the developing device onto a transfer body; a detection unit configured to detect operation information of the image forming apparatus; and a controller configured to cause the voltage application device to apply a pulsed voltage to the charging member during a non-image-forming operation of the image forming apparatus, wherein the controller is configured to control a number of executions for which the pulsed voltage is applied on the basis of the operation information detected by the detection unit.
