摘要： 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.

摘要： A developing device includes a developing chamber provided with a developing roller that conveys toner to a developing area, and a toner regulating member that is in contact with a surface of the developing roller; and a toner container that contains the toner. An opening that allows the developing chamber and the toner container to communicate with each other is closed by a seal member that prevents the toner in the toner container from flowing into the developing chamber, and the seal member is removable from the opening. Spherical resin particles are provided at least in a contact portion between the developing roller and the toner regulating member. A Martens hardness of the spherical resin particles is 0.5 N/mm2 or higher and 45 N/mm2 or lower, and a restoring elastic power of the spherical resin particles is 70% or higher.
