    摘要: A developer conveying mechanism includes a pipe-shaped conveying path that conveys developer and includes a discharge port formed in part of a side surface thereof, a shutter that is slidably attached to the pipe-shaped conveying path and that is selectively arranged at a closing position overlapping with the discharge port and an opening position retreated from the discharge port, a seal member that is fixed to a seal affixing surface of the shutter, and a biasing member that biases the shutter toward the closing position. The shutter includes the seal affixing surface, which is a flat surface, and a pair of engagement portions that are opposite to each other across the seal affixing surface in a circumferential direction of the pipe-shaped conveying path. The pipe-shaped conveying path includes a pair of guide ribs with which the pair of engagement portions slidably engage.

    摘要: A toner case includes a case main body, a transmission member, and a cover. The case main body contains a toner and rotates around a rotation axis line. The transmission member is attached to an outer circumferential face of the case main body and configured to transmit rotation driving force to the case main body. The cover is configured to cover an opening part arranged at the case main body. The case main body includes a rotation restricting part and a movement restricting part. The rotation restricting part is configured to restrict a rotation of the transmission member with respect to the case main body. The movement restricting part is configured to restrict a movement in a direction of the rotation axis line of the transmission member with respect to the case main body. The transmission member is positioned between the cover and the movement restricting part.

    摘要: A toner case includes a case main body, a cover, and an agitating member. The case main body is configured to contain a toner and to rotate. The cover is configured to cover an opening part arranged at the case main body and to maintain a rotation stop state when the case main body rotates, the cover having a communication space which communicates with an inside space of the case main body via the opening part. The agitating member is configured to rotate integrally with the case main body and to agitate the toner in the communication space.

    摘要: A developer storage container (30) includes: a container body (31); a lid (32); a stirring member (34); and an input gear (36). The container body includes: a bottom portion (310); an opening (31 P) extending in a longitudinal direction thereof; a first sidewall (31R) and a second sidewall (31L); and a storage space (30S) for storing developer therein. The second sidewall includes a bearing portion (312) disposed to face the storage space. The first sidewall includes: a shaft hole (313S) communicating between an outside of the container body and the storage space; and a support portion (313T) supporting a distal end of a coupling (342) of the stirring member from therebelow to prevent the stirring member from falling onto the bottom portion, in a state in which a distal pivot portion (341) of the stirring member is inserted into the bearing portion, and the coupling is disposed facing the shaft hole.

    摘要: A developer cartridge includes a casing and a developer container detachably attached to the casing. The developer container includes a tubular member, a conveyor, an end member, and a sealing member. The tubular member is configured to contain developer therein and has an axis. The conveyor is disposed in the tubular member and is configured to convey the developer toward one end of the tubular member along the axis. The end member is disposed at a predetermined distance away from the one end of the tubular member. The sealing member is attached to an outer peripheral surface of the end member and an outer peripheral surface of the tubular member, and is configured to be broken with rotation of at least one of the tubular member and the conveyor.
