摘要： A developing device includes an accommodating portion for accommodating toner, a developing roller and a stirring member. The developing device is for use with an image forming apparatus and detachably mounts a replenishing container for replenishing the toner. The accommodating portion includes a receiving opening through which the toner replenished from the accommodating portion is received in the accommodating portion, the receiving opening being provide on a first end side of the accommodating portion with respect to a rotational axis direction of the developing roller. An opening area of the receiving opening when the developing device is viewed in the rotational direction is wider than the opening area of the receiving opening when viewed in a direction perpendicular to the rotational axis direction.

摘要： An image forming apparatus includes a first unit including an image bearing member and a second unit. The second unit includes a developing roller to supply the toner to the image bearing member, a mounting portion in which the replenishing container is dismountably mounted and an accommodating portion to accommodate the toner replenished from the replenishing container. The second unit is movable between a first position where the developing roller contacts the image bearing member and a second position where the developing roller separates from the image bearing member. When a moving direction in which the second unit moves from the first position toward the second position is defined as a separating direction, the second unit is urged in the separating direction by a force which the mounting portion receives from the replenishing container when the replenishing container is mounted to the mounting portion.

摘要： A cartridge includes a photosensitive drum unit having a photosensitive drum and a drum frame supporting the photosensitive drum so that the photosensitive drum is rotatable about a rotational axis. The photosensitive drum unit also includes a positioned portion configured to contact a positioning portion of a main assembly so that the photosensitive drum unit is positioned relative to the main assembly and a rotation-prevented portion configured to prevent the photosensitive drum unit from rotating relative to the main assembly. The cartridge further includes a developing unit having a developing roller configured to supply toner to the photosensitive drum. The developing unit also includes a memory unit having an electrical contact surface configured to contact a main assembly contact of the main assembly. When viewed in the direction of the rotational axis, a line segment connects the center of the positioned portion and a center of the rotation-prevented portion, a linear line passes through the electrical contact surface and is perpendicular to the electrical contact surface, the line segment and the linear line intersect with each other at an intersection, and a distance between the center of the positioned portion and the intersection is longer than a distance between the center of the rotation prevented portion and the intersection.

摘要： An image forming system includes a toner container and an image forming apparatus to which the toner container is detachably mountable. The image forming apparatus includes a mounting portion to which the toner container is detachably mountable. The toner container includes an accommodating portion configured to accommodate toner, a discharge portion provided with an opening for discharging the toner in the accommodating portion to outside of the toner container, a rotatable member rotatable, relative to the discharge portion, about a rotational axis in a first rotational direction and a second rotational direction that is opposite to the first rotational direction, and a projection provided below the opening of the discharge portion, the projection having inner peripheral surface such that, when the toner container is oriented in a predetermined direction in which the rotational axis extends in a direction of gravity and at least a part of the discharge portion is below the accommodating portion, the inner peripheral surface faces inward in a radial direction of an imaginary circle centered on the rotational axis.

摘要： A cartridge that is mountable to an apparatus main assembly of an image forming apparatus, the cartridge includes a developing roller; a frame supporting the developing roller; a movable part movably supported by the frame and movable to a first position and to a second position relative to the frame; and an elastic part provided between the frame and the movable part to urge the movable part. The movable part includes a first force receiving part that receives force from the apparatus main assembly, in a direction of moving from the first position to the second position, and a second force receiving part that receives force from the apparatus main assembly, in a direction of moving from the second position to the first position. When the movable part receives force from the apparatus main assembly at the first force receiving part and is at the second position, the movable part receives urging force from the elastic part in a direction of moving the movable part from the second position to the first position.

摘要： In a cartridge structure employing an inclinable coupling member engaging with a rotational force transmitting portion of an electrophotographic image forming apparatus, the coupling member is unable to engage with the rotational force transmitting portion of the electrophotographic image forming apparatus when the mounting and dismounting direction and the developing/spacing direction relative to the electrophotographic image forming apparatus of different from each other. Under the circumstances, a coupling lever contacting and retracting relative to the coupling member in interrelation with the mounting and dismounting operation of a developing cartridge B1, and a coupling spring for the coupling lever to apply an urging force to the coupling member are provided.

摘要： An attached portion of an image forming apparatus includes a rotating member of which at least a part is exposed outside the image forming apparatus when the developer container is attached, and a rotation restricting mechanism that is movable between a restricting position to restrict rotation of the rotating member and an allowable position to allow rotation of the rotating member, and includes a restricting member that is at the restricting position when the developer container is not attached. The developer container is attached to the attached portion so that the discharging portion engaging portion and the shutter engaging portions are engaged with the frame engaged portions and the rotating member engaged portions respectively when the container shutter is in the close state, and the restricting member moves from the restricting position to the allowable position when the developer container is attached to the attached portion.

摘要： A cartridge for an image forming apparatus includes: a process unit to be used to form an image; a first member including a first resin material; a second member including a second resin material having higher flame retardant capability than the first resin material; and an electrode member including a contact section configured to be supplied with power from an apparatus main body of the image forming apparatus. The electrode member is configured to electrically connect the apparatus main body to the process unit. The second resin material of the second member has a greater density than the first resin material of the first member. The contact section is located in the vicinity of the first and second members and is closer to the second member than to the first member.
