To provide a structure in which, even when the space between a grid and a photosensitive member is narrowed so as to improve charging efficiency, wear of a shutter due to rubbing against the grid during movement of the shutter is suppressed. There is provided a mechanism that withdraws the grid to the discharge electrode side when the opening is covered with the shutter.
