An image forming device includes a main casing, a support member, a plurality of developing cartridges, a handle provided to the support member, and a pair of interfering parts provided at both ends of the support member. Each developing cartridge includes a casing and a developing member supported by the casing. A gap between the pair of interfering parts is narrower than a length of the developing member, and the pair of interfering parts is located between the handle and one of the developing cartridges. Each of the interfering parts has a higher height than the handle.

There is provided an image forming apparatus includes an apparatus body having an opening, an open/close member which opens and closes the opening, and an image forming unit which is drawable to an outside of the apparatus body through the opening. The open/close member includes a restraint member which is movable between a restraint position of restraining movement of the image forming unit and a restraint release position of releasing the restraint, and a moving member which moves the restraint member from the restraint position toward the restraint release position as the open/close member being moved from a close position to an open position. Once the restraint member is moved from the restraint position toward the restraint release position, the restraint member is held at the restraint release position not to be moved from the restraint release position to the restraint position even when the open/close member is moved.

The process unit includes a casing, a developer unit, and a switching unit. The developer unit is movable between an image-forming position and a detached position. The developer unit includes a drive force input unit and a drive force transmitting unit. A drive force is inputted into the drive force input unit from outside of the developer unit. The drive force transmitting unit transmits the drive force. The switching member is for switching the drive force transmitting unit between a transmitting state and an interrupting state. The switching member switches the drive force transmitting unit to the transmitting state when the developer unit is at the image-forming position, and the switching member switches the drive force transmitting unit to the interrupting state when the developer unit is at the detached position.

A holder unit is configured to hold a plurality of photosensitive drums such that the plurality of photosensitive drums are arrayed in a predetermined direction and juxtaposed with each other with a space between neighboring photosensitive drums. A plurality of developing units is held by the holder unit, each is provided in association with each photosensitive drum, and each includes a developing roller displaceable between a contact position where the developing roller is in contact with the photosensitive drum and a spaced position where the developing roller is spaced away from the photosensitive drum. A spacer member has a plurality of retaining portions each in association with each developing unit and configured to retain each developing unit at the spaced position, and a linking portion integral with the retaining portions and configured to connect neighboring retaining portions therethrough in the predetermined direction.

An image forming apparatus is described. The image forming apparatus may include an image forming apparatus body and a photosensitive unit detachably mountable to the image forming apparatus body. The photosensitive unit includes: a frame; photosensitive bodies supported by the frame; cartridges including a developer carrier and detachably mountable to the frame; and a pressing portion provided on the frame for pressing the cartridges to direct the developer carrier toward the corresponding photosensitive body. Each cartridge can shift in the frame to a first attitude pressed by the pressing portion, and a second attitude released from the press of the pressing portion and detachable from the frame. The image forming apparatus body is provided with an abutment portion abutting the cartridge in the second attitude thereby bringing the cartridge into the first attitude when the photosensitive unit is mounted to the image forming apparatus body.
