A cartridge is mountable in and dismountable from a main assembly of an image forming apparatus, in which the main assembly includes an opening and an openable member including a discriminating portion. The cartridge includes a process unit including a rotatable photosensitive member and a developing roller configured to supply toner to the photosensitive member, and a developer storage unit configured to store a developer. The developer storage unit is provided with a discharge opening for permitting discharge of the stored developer to the process unit and is mountable to and dismountable from the process unit. The developer storage unit is provided with a portion-to-be-discriminated provided so as to be engaged with the discriminating portion of the openable member when the cartridge is mounted in the main assembly and the openable member is in a closed position.

A lighting tool for a vehicle includes a first light emission unit that reflects first light emitted from a first light source using a reflector and emit the first light reflected by the reflector to a side behind a vehicle, and a second light emission unit configured to guide second light emitted from a second light source using a light guide lens and emit the second light guided by the light guide lens to a side behind the vehicle, the first light emission unit emits the first light toward the illumination range behind the vehicle, and the second light emission unit is disposed in plural in a vehicle width direction and selectively emits the second light for each of the illumination regions which are divided in the vehicle width direction so as to overlap the illumination range.

Lighting tool for vehicle and vehicle rearward illumination system

A developing device includes a developing member to carry developer stored by a developing frame, and a regulating blade having a support plate fixed to the developing frame, a plate-like member, and a regulating member. One end portion of the plate-like member is opposed to the developing member, and the other end portion is welded to the support plate. The regulating member is fixed to a plate-like member surface, and contacts the developing member to regulate a developer thickness on a developing surface. The regulating member is provided with a recessed portion recessed at a regulating member end portion. The regulating member end portion is lower than a regulating member central portion. A plate-like member region welded to the support plate is located at the plate-like member other end portion and overlaps the regulating member central portion and the regulating member end portion at which the recessed portion is provided.

Developing device

A cartridge detachably mountable to a main assembly of an image forming apparatus includes a photosensitive member unit including a photosensitive drum; a sheet configured to remove a deposited matter from a surface of the drum, the sheet being in contact with the surface of the drum at an end portion of the drum with respect to a rotational axis direction of the member; and a developing unit detachably mounted to the member unit, the developing unit including a developing roller configured to supply toner to the drum, and a storage portion configured to store the deposited matter removed from the surface of the drum by the sheet.

Cartridge

Process cartridge for image forming apparatus

A cartridge includes a projection portion provided in a first region of an upper surface of a frame in a vertical direction. The projection portion projects more upward than second regions between which the first region is interposed. An inside of the projection portion is a space that is part of a developer accommodating portion. The projection portion is configured to pass through a space under an abutting portion while being elastically deformed by the abutted portion being pressed by the abutting portion after the cartridge is transitioned from the first posture to the second posture in accordance with movement of the cartridge in the attaching direction.

A coupling member for an image forming apparatus cartridge includes a first end portion including an outer surface and a plurality of surfaces forming a recess extending in a direction from the outer surface toward the rotational axis. The plurality of surfaces include a first surface, a second surface opposite to the first surface, and a third surface extending between the first surface and the second surface. As viewed in a direction toward the recess and perpendicular to the rotational axis, the third surface faces toward outside of the recess, and both of the first and second surfaces are sloped with respect to a plane that is perpendicular to the rotational axis such that a distance measured along a direction of the rotational axis between the first and second surfaces decreases as a distance along the first and second surfaces from the outer surface increases.

A developing apparatus for use in an image forming apparatus includes a developing frame, a rotatable developing member, a regulation blade to regulate developer borne on a developing member surface, and a seal member to prevent developer from leaking outside the developing frame. The regulation blade includes a support plate, a plate-shaped member, and a regulation member. The seal member is fixed to a facing surface of the plate-shaped member, is arranged at a plate-shaped member end portion, is arranged side by side with the regulation member in a rotational axis direction, contacts an end surface of the regulation member, and is disposed between the plate-shaped member and the developing member in a direction intersecting with the rotational axis direction. The plate-shaped member is welded to a region of the support plate excluding a region outside the end surface of the regulation member in the rotational axis direction.

With a structure in which a coupling member includes a sphere providing a center of inclination (pivoting), a rotational force transmitted member has an opening have a diameter smaller than that of the sphere, and the coupling member is prevented from disengaging from rotational force transmitted member by contact of inner edge of the opening to the sphere, the inner edge of the opening may limit an inclinable (pivotable) angle range of the coupling member. In a state that a pin that is a shaft portion is inserted in a hole that is a through-hole provided in a coupling member, opposite end portions of the pin are supported by a driving side flange, which is a rotational force transmitted member. The coupling member, the driving side flange, and the pin are connected in this manner, and the pin contacts the inside of the hole without limiting the inclinable angle range.
