    Abstract: An image forming apparatus includes an image bearing member, a transfer roller, a power feeding rotary member, and a controller. The controller is configured to execute the cleaning mode such that a period in which the cleaning mode is executed comprises a first application period during which a reverse polarity bias having a polarity reverse to that of the transfer bias is continuously applied to the power feeding rotary member, and a second application period during which a same polarity bias having a same polarity with that of the transfer bias is continuously applied to the power feeding rotary member.

    Abstract: An image forming apparatus includes first and second rotating members, a setting unit, and first and second image forming units. The first rotating member rotates at a first period T1. The second rotating member rotates at a second period T2. The setting unit sets the first period T1 and the second period T2 so that T1 and T2 meet a relation T2=(n+0.5)×T1 (n is a positive integer). The first image forming unit forms a first image on the second rotating member in an x-th rotation (x is a positive integer) using first data obtained from print data and using the first rotating member. The second image forming unit forms a second image on the second rotating member in an (x+y)-th rotation (y is an odd positive integer) using second data obtained from the print data and using the first rotating member.

    Abstract: A developing device usable with an electrophotographic image forming apparatus, the apparatus including a driving shaft rotatable by a motor and having a rotating force applying portion, and a movable member, the developing device being mountable to the movable member, and the developing device being movable in a direction substantially perpendicular to an axial direction of the driving shaft in response to movement of the movable member in one direction with the developing device mounted to the movable member, the developing device includes i) a developing roller for developing an electrostatic latent image formed on an electrophotographic photosensitive drum, the developing roller being rotatable about an axis; and ii) a coupling member for transmitting a rotating force to the developing roller, the coupling member including, a rotating force receiving portion engageable with the rotating force applying portion to receive a rotating force from the driving shaft, and a rotating force transmitting portion for transmitting the rotating force received through the rotating force receiving portion to the developing roller, the coupling member being capable of taking a rotational force transmitting angular position for transmitting the rotational force for rotating the developing roller to the developing roller, a pre-engagement angular position which is taken before the coupling member is engaged with the rotating force applying portion and in which the coupling member is inclined away from the rotational force transmitting angular position, and a disengaging angular position which is taken for the coupling member to disengage from the driving shaft and in which the coupling member is inclined away from the rotational force transmitting angular position in a direction opposite to the pre-engagement angular position; wherein in response to a movement of the developing device when the movable member moves in the one direction, the coupling member moves from the pre-engagement angular position to the rotational force transmitting angular position to be opposed to the driving shaft, and wherein when the movable member makes a further movement in the one direction from a position where the coupling member is opposed to the driving shaft, in response to the further movement, the coupling member is disengaged from the driving shaft by moving from the rotational force transmitting angular position to the disengaging angular position.
