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

[Problem] To provide a form of a container for use with an image forming apparatus [Solution] A container for use with an image forming apparatus and for accommodating a content of powder or a liquid, the container includes an accommodating portion configured to accommodate the content; an end portion including a discharging portion which includes a discharge opening for permitting discharge of the content to an outside of the container and a passage configured so that the content passes through the passage toward the discharge opening, and including a shutter configured to be movable relative to the discharging portion between a shielding position where the shutter shields the discharge opening and an open position where the shutter opens the discharge opening; and a cap mounted to the end portion so as to cover at least a part of the end portion and configured to be dismounted from the end portion by being rotated relative to the end portion.

Container having a shutter and a cap mounted to the shutter to cover an end portion of the container

Provided a toner container having: a storage portion configured to store toner; a nozzle portion having a discharging port configured to discharge, outside the toner container, toner stored in the storage portion, the nozzle portion being fixed to the storage portion such that the nozzle portion and the storage portion are aligned in a first direction; and a loosening member configured to loose toner, the loosening member including at least a portion provided in the storage portion, wherein the loosening member is swingable relative to the storage portion about a swing axis extending in a second direction crossing the first direction.

Toner container

An image forming apparatus that includes an actuator to drive a stirring member, an indicating unit to execute a remaining toner amount indication based on an output value from a first detection unit, and a control unit control the actuator, the first detection unit, and the indicating unit. A control unit executes (i) a first control of controlling the actuator to start driving of the stirring member based on a detection, by a second detection unit, of movement of an opening and closing member from the open position to the closed position, (ii) a second control of controlling the first detection unit to output the output value, and (iii) a third control of controlling the indicating unit to execute the remaining toner amount indication.

Image forming apparatus

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.

Image forming apparatus and image forming system

Toner pack

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.

Developing device and image forming apparatus

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.

A control memberfor controlling transmission and blocking of a rotational force by a clutch is rotatably supported by a supporting member which supports a developing frame. a locking portion provided on the control memberrotates between a position retracted from a locked portion of the clutch and a position for engaging with the locked portion.

Cartridge having a member for transmitting a driving force for rotating a developing roller

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.
