A color laser printer includes chargers for charging the photosensitive drums as an image carrier on which a toner image for each print color is formed. Each charger is supported by a frame member provided rotatably around a central axis of a photosensitive drum. When a closing door is moved from a closed position where an opening portion is closed to an opened position where the opening portion is opened, the frame member is moved in conjunction with the operation, from a first position where the charger charges the photosensitive drum to a second position where a part of the opening portion in the photosensitive drum is covered.
