Abstract: A toner cartridge includes a cartridge case, a stirring paddle and a stirring sheet. In the cartridge case, a toner stirring chamber is formed. The stirring paddle is rotatably installed in the stirring chamber. The stirring sheet is rotatable together with the stirring paddle in the stirring chamber. The cartridge case has a toner supply port. The stirring sheet protrudes outward in a radial direction from a rotational locus drawn by a tip end of the stirring paddle. When the stirring paddle is positioned at a specific rotational phase, the stirring sheet blocks the supply port.

Abstract: An image forming apparatus includes a toner case and an attachment part. The toner case includes a discharge shutter movable between a first closing position where a discharge port is closed and a first opening position where the discharge port is opened. The attachment part includes a replenishment shutter movable between a second closing position where a replenishment port is closed and a second opening position where the replenishment port is opened. As the discharge shutter moves from the first closing position to the first opening position, the discharge shutter presses the replenishment shutter to move the replenishment shutter from the second closing position to the second opening position. As the discharge shutter moves from the first opening position to the first closing position, the discharge shutter presses the replenishment shutter to move the replenishment shutter from the second opening position to the second closing position.

Abstract: A developing device includes a development casing, a developer carrying member, and a regulating blade. The development casing has an opening part. The developer carrying member has a developing area. The development casing has a blade facing part. The regulating blade includes a fixed part and a regulating part, and a space between the regulating part and the blade facing part is larger than a space between the fixed part and the blade facing part. The developing device further includes a blade seal member. The blade seal member is disposed between the regulating blade and the blade facing part, and is glued to an upstream side surface of the regulating part in the rotation direction, so as to seal a gap between the regulating blade and the blade facing part.

Abstract: The developing device includes a development container, a developer carrier, and a restricting blade. The development container has an opening. The developer carrier has a development area. The development container includes a pair of side frames, and a pair of side wall portions. In each of the pair of side wall portions, a seal member insertion hole extending through in the rotation-axial direction is formed at a position facing an end edge of the restricting blade in the rotation-axial direction. The developing device includes a blade-side side seal inserted in the seal member insertion hole to block a gap between the restricting blade and the side wall portion.

Abstract: A developing device includes a development casing, a developer carrying member, a regulating blade, a pair of pressing members, and a blade seal member. The development casing has an opening part. The developer carrying member has a developing area. The blade seal member includes a first layer material and a second layer material. The development casing has facing surfaces. The second layer material has positioning protrusions protruding from the first layer material in a rotation axis direction at positions inside both ends of the first layer material in the rotation axis direction, so as to contact the facing surfaces and be positioned in the rotation axis direction. When the second layer material is positioned in the rotation axis direction, the first layer material is pressed in contact with the pressing members in the rotation axis direction.

Abstract: The developing device includes a development container, a developer carrier, and a cover member. The development container has an opening. The developer carrier has a development area. The cover member, including a front face portion, an upper face portion, a lower face portion, a side face portion, and reinforcing ribs, is removably fitted to the development container such that the developer carrier is covered with at least the front face portion and the upper face portion. With the cover member fitted to the development container, a gap is formed between each reinforcing rib and the development container.

Abstract: In a toner supply device (40), a horizontal transport portion (42) is connected to a vertical transport portion (41). A stirring transport screw (25) includes a rotary shaft (25a) and a supply blade (25c), and transports toner in the horizontal transport portion (42) toward the rotary shaft (25a). A drive input gear (50) inputs a rotational drive force to the rotary shaft (25a). A crank shaft (47) has a central shaft (47a) connected to the drive input gear (50) and is rotated at a lower speed than the rotary shaft (25a), and an eccentric shaft (47c) extending in parallel to the central shaft (47a) from a position radially outward from the central shaft. One end of the toner loosening member (45) is connected to the eccentric shaft (47c), and the toner loosening member (45) is reciprocatingly moved in the vertical direction in the vertical transport portion (41) due to a circumferential movement operation of the eccentric shaft (47c) centered on the central shaft (47a).

Abstract: A toner case includes a case main body, a rotator, a transmitter and a turner. The rotator is stored in the case main body and rotates around a rotation axis. The transmitter transmits rotation to the rotator. A part of the transmitter is exposed to an outside of the case main body. The turner is provided at an outside of the case main body in a rotation axis direction. The turner is turnable between a first posture and a second posture. At least a part of the turner is moved to an outside in the rotation axis direction as the turner turns from the first posture to the second posture. The transmitter moves from a first position to a second position which is arranged at an outside of the first position in the rotation axis direction as the turner turns from the first posture to the second posture.
