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.

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.

Abstract: An image forming apparatus, such as a laser printer, may use high levels of heat to form images, and some elements may expand and contract with changing temperatures. An apparatus may include a heat roller disposed against a pressure roller, with an endless belt member enclosing the pressure roller. The belt member may also have different frictional characteristics on an inside and outside of the roller, such that when peripheral speeds change due to expansion of the pressure roller, the belt member may be configured to slip against the pressure roller, and maintain a frictional relationship with the heat roller (or a printing medium, such as paper, that is pinched between the rollers). Additionally, the rotational speed of an axis of the pressure roller may be adjusted to compensate for the thermal expansion.
