摘要： When toner on an intermediate transfer member is picked up by a cleaning unit by transferring the toner to an image bearing member in a recovery operation, pickup conditions are controlled to be changed on the basis of the ambience detected in performing the recovery operation and such that the toner on the intermediate transfer member is picked up by the cleaning unit while being temporarily retained by a secondary transfer roller.

摘要： In an image forming apparatus of a rotary type, when a pause is made during continuous image formation, the time taken to restart image formation after the pause is shortened so as to reduce stress on the user. In the image forming apparatus, it is determined beforehand whether the next image formation mode is a color mode or a mono mode, and a developing device to be first used in the next image formation mode is moved to a developing standby position.

摘要： In a rotary-type image forming apparatus, rotation of a rotary is temporarily stopped at a position where a coupling member and a drive transmission member are engageable with each other, and a developing roller is set in a rotating state. Subsequently, the rotary is rotated so as to bring the developing roller into contact with a surface of a photosensitive drum.

摘要： An image forming apparatus includes a developing device, a detection mode execution unit, and a notice signal generating unit. The developing device supplies a toner bearing member with toner in a container by rotating a toner supply member in a contact manner with the toner bearing member. The detection mode execution unit executes a detection mode in which a predetermined period for changing a toner amount in the foam layer by rotating the toner supply member is provided, a capacitance C1 between the first and second electrode members is detected before the predetermined period, and a capacitance C2 between the first and second electrode members is detected after the predetermined period. The notice signal generating unit generates a low toner amount notice signal in response to an absolute value |C1−C2| of a difference between the capacitances C1 and C2 being smaller than a predetermined threshold.
