`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 mov-
`able 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 apply-
`ing 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 disen-
`gaging 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 posi-
`tion to the disengaging angular position.
