摘要： A developing device which can stably supply a developer to a latent image carrier by preventing the scattered developer from being discharged and thereby preventing the developer from being discharged despite that the amount of developer within the developing device does not increase, and an image forming apparatus using the developing device. A block member serving as a scattered developer discharge prevention member is provided so as to block a path through which the developer scattered as a result of a conveyance operation of a supply screw serving as a developer conveying member moves toward a developer discharge port. Accordingly, the scattered developer is prevented from reaching the developer discharge port and being discharged therefrom.

摘要： A developing device includes a rotator that rotates around a shaft, and a bearing element that supports the shaft to a housing. A sliding element formed of a composite material that contains self-lubricating thermoplastic olefin resin as a base material is used as the bearing element. The sliding element formed of the composite material has at least a ratio of numerical values of “Rockwell hardness”/“bending elastic modulus” in a range from 25 to 45, and provides a sliding surface of which a frictional coefficient is lower than that of the sliding element formed of the base material.

摘要： A powder container is for use with an image forming apparatus, and the image forming apparatus includes a driving protrusion that is rotatable and that protrudes toward an upstream side in an insertion direction in which the powder container is inserted. The powder container includes a container body to store powder, a cap attached to the container body, and a transmitted structure provided on the cap to contact the driving protrusion. The transmitted structure extends outward from an outer circumference of the powder container. The cap is rotatable relative to the container body in a predetermined angular range. The rotation of the cap relative to the container body is restricted so that the container body rotates along with the rotation of the cap when the rotation of the cap exceeds the predetermined angular range.

摘要： An image forming apparatus includes a developing device; a developer conveyance device including a developer container, a developer reservoir to receive developer discharged from the developer container, and a positive-displacement pump to discharge, from the developer reservoir, developer supplied to the developing device by alternately generating positive pressure and negative pressure due to volume changes; and a controller to control driving of the positive-displacement pump. When the controller recognizes a developer end state of the developer container, the controller lowers a developer conveyance capability of the positive-displacement pump from a setting used before the developer end state is recognized.

摘要： A powder container is insertable in an image forming apparatus, and includes a main-body interlocking portion that is rotatable and protrudes toward an upstream side in an insertion direction in which the powder container is inserted, the image forming apparatus including an identifier protrusion that protrudes toward the upstream side in the insertion direction to identify a type of the powder container. The powder container includes a container interlocking portion configured to interlock with the main-body interlocking portion; and an interlocked portion configured to interlock with the identifier protrusion. The interlocked portion is provided in a front end of the powder container in the insertion direction. The container interlocking portion stands outward from an outer circumference of the powder container. The container interlocking portion and the interlocked portion are rotated integrally.
