Abstract
An image forming apparatus includes an image bearing member on which an electrostatic image is to be formed; a rotatable supporting member, configured to support a developing device for developing the electrostatic image and configured to rotationally move the developing device toward a developing position, provided movably in a rotational axis direction with respect to a main assembly of the image forming apparatus; an urging member for urging the rotatable supporting member in the rotational axis direction. In addition, a regulating portion regulates a position of the rotatable supporting member, with respect to the rotational axis direction, urged by the urging member. The rotatable supporting member includes a first rotatable member provided movably in the rotational axis direction at one end side of the rotatable supporting member with respect to the rotational axis direction, and a second rotatable member provided movably in the rotational axis direction at the other end side of the rotatable supporting member. The urging member urges the first rotatable member and the second rotatable member apart.
