ABSTRACT:
An image forming apparatus is constituted by an image bearing member; a corona charging member including a wire; a heat generating member for generating heat by energization; a shielding member, including the heat generating member, capable of shielding a portion of the corona charging member opposing to the image bearing member from the image bearing member by being moved between the corona charging member and the image bearing member; an energization control member for controlling energization of the heat generating member; and moving member for moving the shielding member to a first position at which the shielding member shields the portion and a second position retracted from the first position. When the shielding member is located at the first position, at least a part of the heat generating member is disposed between the corona charging member and the image bearing member.
