Abstract: Problem to be Solved To further develop a prior art cartridge. [Solution] A cartridge includes a holding movable between a first position for stably holding a second unit in a spaced position by a first unit and a second position, and a contact force receiving portion capable of receiving a contact force for moving the holding portion from the first position toward the second position to move the second unit to a developing position, when the second unit is in the spaced position.

Abstract: 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.

Abstract: [Task] To further develop conventional technique.

Abstract: [Task] To further develop conventional technique. [SOLUTION] An image forming apparatus includes a main assembly; 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 201 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.

Abstract: A cartridge includes a photosensitive member, a charging member configured to charge the photosensitive member, a first unit including the photosensitive member and the charging member, a developing member configured to deposit toner onto the photosensitive member, and a second unit including the developing member. A holding portion is movably supported by the first unit or the second unit, with the holding portion being configured to restrict a relative position between the first unit and the second unit, the holding portion being movable between a first position for holding the second unit in a spaced position by the first unit and a second position for holding the second unit in a developing position by the first unit.

Abstract: 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.

Abstract: 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.

Abstract: An image forming apparatus includes: a cartridge; a developer container, in which the cartridge allows the developer container to be movable between first and second positions; an apparatus main body including an opening through which the cartridge passes when the cartridge is attached and an opening and closing member movable between an open position to open the opening and a close position to close the opening; and a moving member moving to be at different positions between a case where the developer container is attached at the first position and a case where it is attached at the second position, and when the developer container is attached at the first position, the moving member is at a position of preventing movement from the open position to the close position, and when it is attached at the second position, the moving member is at a position of allowing the movement.

Abstract: A photosensitive member unit includes photosensitive drums and a frame including positioning portions. One and the other end shaft portions of the photosensitive drums are movable between first positions in which the above-mentioned one and the other end shaft portions are positioned by the positioning portions and second positions in which the above-mentioned one end of the other end shaft portions are not positioned by said positioning portions. The photosensitive member unit includes a plurality of mounting portions which are provided in the frame and to which developing units including developing members capable of supplying toner to the photosensitive drums are mountable, and from which the developing units are dismountable without dismounting the photosensitive drums from the frame, in a state that the above-mentioned one and the other end shaft portions are positioned by the positioning portions.
