Abstract
A charging device for electrically charging a photosensitive member, includes: a discharging electrode; a casing provided with an opening; a grid provided at the opening; a sheet-shaped shutter; a moving portion; a connecting portion; a winding-up portion; an urging portion; a first supporting portion; a second supporting portion; and an operating portion. The winding-up portion is configured to wind up, when the shutter is closed, the shutter so that a surface of the shutter opposing the photosensitive member is an outermost surface. When movement of the shutter in the opening direction is completed, the operating portion is covered with the shutter. When the connecting portion is separated from the moving portion, a leading end portion of the shutter with respect to the closing direction is movable toward a downstream side of the operating portion with respect to the opening direction by a winding-up force by the urging portion.
