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.

摘要： A powder container is insertable in an image forming apparatus. The powder container includes a plurality of transmitted surfaces, at least one of the transmitted surfaces being configured to contact a first protrusion of the image forming, apparatus, the first protrusion being rotatable and protruding toward an upstream side in an insertion direction in which the powder container is inserted. The transmitted surfaces stand outward from an outer circumference of the powder container so that one of the transmitted surfaces is connected to another transmitted surface adjacent to the one of the transmitted surfaces by an inclined surface.

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： 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.

摘要： A powder container is insertable in an image forming apparatus. The powder container includes a plurality of transmitted surfaces, at least one of the transmitted surfaces being configured to contact a first protrusion of the linage forming apparatus, the first protrusion being rotatable and protruding toward an upstream side in an insertion direction in which the powder container is inserted. The transmitted surfaces stand outward from an outer circumference of the powder container so that one of the transmitted surfaces is connected to another transmitted surface adjacent to the one of the transmitted surfaces by an inclined surface.

摘要： A developing device includes a developer bearer to carry, by rotation, developer including toner and magnetic carrier to a development range facing a latent image bearer to bear a latent image. The developer bearer includes a magnetic field generator having multiple magnetic poles and a cylindrical developing sleeve to rotate and bear developer on an outer circumferential surface thereof with magnetic force of the magnetic field generator disposed inside the developing sleeve. The developing sleeve receives development voltage including an AC component having a frequency of 2.0 kHz or lower, and a duty ratio of a component having a polarity opposite a toner normal charge polarity of the AC component is within a range from 4% to 20%.
