A cartridge includes a casing, a photosensitive drum rotatably supported by the casing, a charging roller rotatably supported by the casing, and a developing roller rotatably supported by the casing. A shield member is supported by the casing and including a shield portion capable of covering a photosensitive member, the shield member being movable between a first position in which the shield portion covers the photosensitive member and a second position in which the photosensitive member is more exposed to outside of the cartridge by the shield portion than when the shield member is in the first position. An engaging portion is engageable with the shield member to hold the shield member in the second position when the shield member is in the second position, and a force receiving portion is provided for receiving an external force to disengage the engagement between the engaging portion and the shield member.

Cartridge and image forming apparatus

An image forming apparatus includes a main assembly and a plurality of process cartridges detachably mountable to the main assembly. The process cartridges each includes a photosensitive member, a first frame rotatably supporting the photosensitive member, a developing member for depositing toner onto the photosensitive member, and a second frame rotatably supporting the developing member and movable relative to the first frame between a developing position for the developing member to deposit the toner onto the photosensitive member and a retracted position in which the developing member is more remote from the photosensitive member than in the developing position. The apparatus further includes a connecting member connecting at least two of the second frames of the process cartridges and removable from at least one of the process cartridges and from the main assembly.

Image forming apparatus, process cartridges, and connecting member

A developer container includes a container member, a connector member attached to the container member, and a discharge path forming member connected to the container member and to discharge a developer from the container member. The connector member includes an inserted portion, and an engaged portion. The discharge path forming member includes an insertion portion inserted into the inserted portion, and an engaging portion provided correspondingly to the engaged portion. The engaged portion and engaging portion come to a state of mutual engagement by a relative rotation between the connector member and the discharge path forming member about a predetermined rotation axis, in a state where the insertion portion is inserted into the inserted portion. In the engaged state, the engaged portion and engaging portion restrict a relative movement of the connector member and the discharge path forming member in the direction of the rotation axis.

Developer container and manufacturing method for developer container

An image forming apparatus to which a toner container is detachably mountable includes a mounting portion to which the toner container is detachably mountable and which includes a receiving port for receiving toner supplied from the toner container, a passage for permitting passing of the toner received through the receiving port and provided with a through hole, and a filter portion provided so as to cover the through hole and for permitting passing of air; and an accommodating portion configured to accommodate the toner received through the receiving port. At least a part of the through hole overlaps with the receiving port as viewed in a horizontal direction perpendicular to a direction of gravitation.

Toner pack

A cartridge includes a photosensitive member, a charging member capable of charging the photosensitive member, and a developing member for depositing toner onto the photosensitive member. A unit includes the developing member and is movable between a developing position in which the toner is capable of being deposited onto the photosensitive member from the developing member and a spaced position in which at least a part of the developing member is spaced from the photosensitive member. The cartridge further includes a contact force receiving portion for receiving a contact force for moving the unit to the developing position when the unit is in the spaced position. The cartridge also includes a spacing force receiving portion for receiving a spacing force for moving the unit to the spaced position when the unit is in the developing position.

Electrophotographic image forming apparatus and cartridge

A developer container includes a pouch, a communication member, and a cap. A marking including an arrowhead part and a parting line are formed on an outer peripheral surface of the cap. A rear end of the arrowhead part is disposed between a first position that is a position 45° upstream from a reference position in a direction of rotation and a second position that is a position 45° downstream in the direction of rotation. The rear end of the arrowhead part overlaps the parting line.

Developer container and image forming system including detachable cap

A container for accommodating a content of powder or a liquid includes an accommodating portion; an end portion including a rotatable member and a discharging portion which includes a discharge opening and a passage, wherein the end portion is on a side opposite from the accommodating portion with respect to a rotational axis direction; and a flange portion extending in a radial direction of a phantom circle about the rotational axis, wherein as viewed in the rotational axis direction, an outer edge of the flange portion includes an arcuate portion which is on an outermost side of the end portion with respect to the radial direction and which is formed along the phantom circle about the rotational axis and includes a connecting portion which connects a first point and a second point on the phantom circle and which is provided in a region inside the phantom circle.

Container

A cartridge includes a photosensitive member, a developing member for depositing toner onto the photosensitive member, and a coupling member capable of receiving a driving force for rotating the developing member. The cartridge also includes a movable portion movable between a driving force transmitting position for permitting transmission of the driving force from the coupling member to the developing member and a driving force interrupting position for interrupting the transmission of the driving force from the coupling member to the developing member. A holding portion is provided for holding the movable portion in the driving force interrupting position when the movable portion is in the driving force interrupting position. The movable portion is capable of taking the driving force transmitting position and the driving force interrupting position in a state where the developing member is in a position where the toner is capable of being deposited on the photosensitive member.
