摘要： An image forming apparatus includes a photosensitive member; a charging member contactable to said photosensitive member to electrically charge said photosensitive member; applying means applying a charging bias voltage to said charging member; detecting means detecting a current flowing between said charging member and said photosensitive member; a controller for controlling said image forming apparatus to execute an operational mode for removing an electric discharge product deposited on a surface of said photosensitive member, in the case that detecting means detects a current not lower than a predetermined value when a voltage lower than a voltage at which an electric charge starts between said photosensitive member and said charging member is applied to said charging member.
