摘要： An image forming apparatus (1) includes an image bearer (12), a first driver (61) to rotate the image bearer (12), a developing device (13) including a developing roller (13a), a second driver (62) to rotate the developing roller (13a), and a controller (60) to control the first driver (61) and the second driver (62) and set a linear speed ratio (X) of the developing roller (13a) relative to the image bearer (12). The controller (60) executes first driving in which the developing roller (13a) rotates with rotation of the image bearer (12) stopped in an idle time and executes second driving for a predetermined period (D2) subsequent to the first driving. The linear speed ratio (X) is set to a first ratio (X1) smaller than 1 in the second driving and to a second ratio (X2) equal to or greater than 1 in image formation.

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.
