Between the optical box and the cover member, the cover member is opposed to the moving unit.

An image forming apparatus includes a photoconductor, a bearing body, an abutting portion, a support frame, an exposure device, and an urging body. The photoconductor includes a shaft portion at an end portion. The bearing body is configured to receive the shaft portion. The abutting portion is coupled to the bearing body. The support frame is configured to support the abutting portion and the bearing body. The exposure device faces the photoconductor, abuts on the abutting portion, and includes a light source exposing the photoconductor to light. The urging body is configured to press the exposure device toward the support frame, urge the abutting portion toward the bearing body and the shaft portion, and urge the bearing body toward the support frame.

An image forming apparatus includes a photoconductor, an exposure device, and a shutter assembly. The exposure device includes a light source configured to expose the photoconductor. The light source is repositionable between a proximity position at a first distance from the photoconductor and a separation position at a second distance from the photoconductor. The first distance is less than the second distance. The shutter assembly is configured to move away from the light source in response to the light source moving toward the proximity position. The shutter assembly is configured to move to cover the optical path of the light source in response to the light source moving toward the separation position.

An image forming apparatus includes: a rotatable image carrier on an outer circumferential surface of which an image is to be formed and that is movable in a rotation axis direction between an image forming position and a maintenance position; a light-emitting unit including a base member extending in the rotation axis direction of the image carrier, and plural light-emitting devices provided on the base member and configured to apply light to the outer circumferential surface of the image carrier, the light-emitting unit being configured to move together with the image carrier in the rotation axis direction; and a supporting unit configured to move together with the image carrier in the rotation axis direction and to support the light-emitting unit when the image carrier and the light-emitting unit are at the maintenance position and the light-emitting unit is disabled from being positioned with respect to the image carrier.

An exposure device includes: at least one light emitter that includes a substrate and a light-emitting device disposed on the substrate; and a position adjuster that includes a contact member having an outer periphery in contact with the substrate, a support member that rotatably supports the contact member, and at least one mover that is in contact with the support member to move the support member in a light emission direction of the light emitter.

An image forming apparatus includes a first image forming unit including a rotatable first image carrier and a first light-emitting unit, the first light-emitting unit including a first base member and plural first light-emitting devices, the first base member extending in an axial direction of the first image carrier, the plural first light-emitting devices being provided on the first base member and being configured to apply light to an outer circumferential surface of the first image carrier; and a second image forming unit including a rotatable second image carrier and a second light-emitting unit, the second light-emitting unit including a second base member and plural second light-emitting devices, the second base member extending in an axial direction of the second image carrier, the plural second light-emitting devices being provided on the second base member and being configured to apply light to an outer circumferential surface of the second image carrier. A direction of detaching and attaching of the first light-emitting unit from and to the first image forming unit and a direction of detaching and attaching of the second light-emitting unit from and to the second image forming unit are different from each other.

The present invention provides an image forming apparatus including: a first moving member pressed and moved by an openable/closable member when the openable/closable member is opened, and switching a cartridge from a state where the cartridge is positioned in an image forming position to a state where the positioning is released; and a second moving member pressed and moved by the openable/closable member when the openable/closable member is opened, and moving the exposure member from an exposure position to a retracted position, wherein when the positioning of the cartridge is released, a reaction force applied from the first moving member to the openable/closable member reaches a first peak, when the exposure member is moved to the retracted position, a reaction force applied from the second moving member to the openable/closable member reaches a second peak, and timing of the first peak is different from timing of the second peak.

In an image forming apparatus having a housing; a cartridge including an image bearing member and capable of being attached/detached to/from the housing; a discharging exposure unit having a light source member and a light guide member, which forms a light guide path guiding light from the light source member so as to be emitted to the image bearing member, and exposing the image bearing member; and an opening/closing member capable of being opened/closed and provided on a surface on which an opening portion, through which the cartridge is inserted/removed in the housing, is provided so as to cover the opening portion, wherein the light source member is provided so as to be exposed to a surface of the housing opened/closed by the opening/closing member and be capable of being attached/detached to/from the light guide member.

An image forming apparatus includes a photosensitive member that is rotatable, a substrate, a lens array, a holder, and a conductive member provided on the holder. The substrate includes a plurality of light-emitting elements, a driver integrated circuit (IC), and a wiring pattern. The plurality of light-emitting elements is arrayed in a rotational axis direction of the photosensitive member to emit light to which a surface of the photosensitive member is exposed. The driver IC drives the plurality of light-emitting elements. The wiring pattern includes a supply line that supplies power to the driver IC and a ground wire that grounds the driver IC. The lens array collects the light emitted from the plurality of light-emitting elements on the photosensitive member. The holder holds the substrate and the lens array, is grounded, and is made of metal. The conductive member electrically connects the holder and the ground wire.

An image forming apparatus includes an image bearer, an exposure device, a (hive device, a cleaning body, and an exposure device holder. The exposure device is disposed on a motion trajectory between an exposure position and a retracted position and emits light to the image bearer via a lens having a lens surface at the exposure position. The drive device causes the exposure device to move between the exposure position and the retracted position. The cleaning body disposed on the motion trajectory of the exposure device tilts a cleaning surface when contacting with the lens surface of the exposure device. The exposure device holder supports the exposure device while changing an attitude of the exposure device such that the lens surface remains in contact with the cleaning surface of the cleaning body when the exposure device moves from the retracted position to the exposure position.
