A process cartridge is detachably mountable to a main assembly of an electrophotographic image forming apparatus. The cartridge includes an electrophotographic photosensitive drum, a developing roller, a drum unit containing the drum, a developing unit containing the roller and being movable so the roller contacts and is spaced from the drum, and a first force receiver receiving a force from a main-assembly first force applier by movement of a door from open to closed positions when mounting the cartridge and a second force receiver movable from a stand-by position by movement of the first force receiver by a force received from the first force applier. The second force receiver takes a projected position receiving a force from the second force applier to move the developing unit so the roller moves out of contact with the drum, the projected position being higher than the stand-by position.

A drum cartridge includes a drum cover movable relative to a photosensitive drum between a first position at which the drum cover covers a part of a circumferential surface of the photosensitive drum and a second position at which the drum cover does not cover the part of the circumferential surface. The drum cover is located at an opposite side of a toner cartridge with respect to the photosensitive drum in a state where the toner cartridge is attached to the drum cartridge and the drum cover is located at the second position. The drum cover is located at the first position in a state where the drum cartridge is attached to a drawer and the drawer is located at a pulled-out position and located at the second position in a state where the drum cartridge is attached to the drawer and the drawer is located at an accommodated position.

An image forming apparatus includes an apparatus main body, a cartridge including a supported portion, a moving member configured to move to the apparatus main body and thereby move the cartridge, the moving member moving to the apparatus main body so as to be in an external position and an internal position, a main body side positioning portion provided on the apparatus main body and configured to, when the moving member is in the internal position, support the supported portion, and an upward inclination portion provided on the apparatus main body and inclined upwardly from a movement direction in which the moving member moves from the external position to the internal position. The upward inclination portion causes the cartridge to move upward with respect to the moving member in a process in which the moving member moves from the external position to the internal position.

An image forming apparatus to form a toner image on a recording material includes a photosensitive member and an optical scanning unit. The optical scanning unit includes an optical scanning unit, an optical box, a cover member, and a moving unit movable to an outside of the image forming apparatus. The optical scanning unit and the moving unit are arranged so that the moving unit and the optical scanning unit are opposed to each other when the moving unit is located in an inside of the image forming apparatus. The optical scanning unit is disposed so as to allow a user to touch the optical scanning unit through a space generated in the inside of the image forming apparatus when the moving unit is moved to the outside of the image forming apparatus. Between the optical box and the cover member, the cover member is opposed to the moving unit.

An image forming apparatus includes a body casing, a pressing member, a process cartridge, and a drawer. The body casing includes a positioning member. The pressing member is disposed inside the body casing. The process cartridge includes a photosensitive drum. The drawer is configured to support the process cartridge and to move, in a sliding direction orthogonal to an axis direction of the photosensitive drum, between an inside position that is a position inside the body casing and an outside position that is a position outside the body casing. The process cartridge includes an engagement portion and a spring. The engagement portion is configured to be positioned by the positioning member. The spring is configured to be pressed by the pressing member such that the engagement portion is pressed toward the positioning member.

A pull-in apparatus configured to pull in a unit toward a predetermined position in an apparatus body includes an arm member, a restriction member, a first action portion and a second action portion. The restriction member is movable between a lock position at which the restriction member restricts movement of the arm member in a first direction and a lock-release position at which the restriction member allows the movement of the arm member in the first direction. Movement of the restriction member from the lock position toward the lock-release position is restricted in a state in which the arm member is at a stand-by position, and is allowed in a state in which the arm member has been moved from the stand-by position in a second direction.

A drawer is moveable between an inner position and an outer position through an opening when a cover is located at an opening position. A waste toner conveying tube is movable in a second direction between a first connection position and a first disconnection position when a drum cartridge is attached to a drawer and the drawer is at the inner position. When the cover moves from a closing position toward the opening position, the waste toner conveying tube moves from the first connection position toward the first disconnection position in conjunction with the movement of the cover. The drawer is movable from the inner position toward to the outer position when the drum cartridge is attached to the drawer, the drawer is at the inner position, and the waste toner conveying tube is at the first disconnection position.

A pull-in apparatus configured to pull in a unit toward a predetermined position in an apparatus body includes an arm member, a restriction member, a first action portion and a second action portion. The restriction member is movable between a lock position at which the restriction member restricts movement of the arm member in a first direction and a lock-release position at which the restriction member allows the movement of the arm member in the first direction. Movement of the restriction member from the lock position toward the lock-release position is restricted in a state in which the arm member is at a stand-by position, and is allowed in a state in which the arm member has been moved from the stand-by position in a second direction.

An image forming apparatus includes: a first housing; a second housing that is supported above the first housing; a mounting part that is provided at at least one of the first housing and the second housing; and a detachable part that is disposed across the first housing and the second housing, the detachable part being mounted detachably with respect to the mounting part and being attachable and detachable in an attaching-detaching direction that connects one side surface and another side surface of the first housing.

According to one embodiment, an image processing device includes a cassette main body, a device main body, a handle, and a pressing member. The cassette main body contains a sheet. The device main body stores the cassette main body retractably in a first direction. The handle is displaceably supported by the cassette main body. The pressing member is supported by the cassette main body. The pressing member presses the device main body in a second direction opposite to the first direction in conjunction with displacement of the handle with respect to the cassette main body.
