摘要： A developing device includes a developer bearer opposed to an image bearer, configured to bear developer and rotate in a direction of rotation of the developer bearer, and configured to develop a latent image on the image bearer and a casing opposed to the developer bearer at a position downstream from an opposed position, at which the developer bearer is opposed to the image bearer, in the direction of rotation of the developer bearer. A casing gap between the developer bearer and the casing continuously decreases or increases from a first end of the developing device to a second end of the developing device across a center of the developing device in a longitudinal direction of the developing device.

摘要： An image forming apparatus includes image bearers, developing devices, developer containers, and developer supply devices. The image bearers are arranged side by side along a movement direction of an intermediate transferor or a sheet. The developing devices, the developer containers, and the developer supply devices are configured to be rearrangeable for each color in the movement direction in a manner that one or each of a developing device, a developer container, and a developer supply device corresponding to each color of the different colors is detached from and attached to the image forming apparatus, separately from a rest of the developing device, the developer container, and the developer supply device. The image forming apparatus is configured to be available for use when colors of the developing device, the developer container, and the developer supply device correspond to each other after rearrangement.

摘要： A developing device includes a developer including a toner, a developer carrier to carry the developer to an image forming area opposing to a latent image bearing member with rotate, a development casing storing the developer, and a developing bias applying member to apply a developing bias to the developer carrier. There is a contacting part to contact a contacting member grounded electrically and disposed at the development casing, and a gap adjusting member to form a gap between the gap adjusting member and the developing carrier. The gap adjusting member is disposed downstream of a rotating direction of the developer carrier. The development casing is conductive, and an insulation member to insulate the gap adjusting member from the development casing is disposed between the gap adjusting member and the development casing.

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 developer conveyance device to transport developer, using a positive-displacement pump to alternately generate positive pressure and negative pressure by changing a volume of an internal space thereof, a destination developer container to which the developer conveyance device transports developer, a sensor provided to the destination developer container, to detect developer in the destination developer container, and a controller to control the positive-displacement pump according to a detection result generated by the sensor. The controller disabled detection of developer by the sensor in a non-detection period that starts from a stop of the positive-displacement pump.
