Abstract: An image forming apparatus includes a casing, photosensitive members arranged along an arrangement direction, and developing cartridges. Each developing cartridge includes a developer carrying member configured to supply a developer to a corresponding one of the photosensitive members. Each photosensitive member is configured to move between an image formation position where an image is formed on the photosensitive member and a retracted position where the photosensitive member is retracted from the developer carrying member. When the photosensitive member is in the image formation position, the photosensitive member is configured to close a path through which a corresponding one of the developing cartridges is attached to and removed from the casing. When the photosensitive member is in the retracted position, the photosensitive member is configured to open the path.

Abstract: An image forming device includes a permitting unit and a moving unit. The permitting unit selectively establishes a first positional relationship in which photosensitive members contact an endless belt and a second positional relationship in which the photosensitive members separate from the endless belt. The moving unit moves a charger between a first position confronting the corresponding photosensitive member at a rear side thereof in a juxtaposed direction and a second position moved away from the first position. The endless belt confronts the photosensitive members at a top side thereof in an orthogonal direction. Each developer cartridge confronts the corresponding photosensitive member at a bottom side thereof. The developer cartridge is attachable to and detachable from a main casing while moved past a front side of the corresponding photosensitive member when the second positional relationship is established and the neighboring charger is in the second position.

The developing unit includes a developer carrying member configured to carry a developer supplied to the photosensitive member. The exposure unit is configured to expose the photosensitive member to form a latent image on the photosensitive member. The covering member is configured to move between a cover position where the covering member covers the exposure member between the photosensitive member and the exposure member and a retracted position where the covering member is retracted from between the photosensitive member and the exposure member. The cover operation mechanism is configured to hold the covering member in the retracted position at least when the exposure member forms the latent image on the photosensitive member.
