    摘要： An image forming apparatus whereby it is possible to prevent unevenness in developing density caused by misalignment between the central axes of a driven side rotational coupling section for rotating a developer carrier and a drive side rotational coupling section for transmitting rotational drive force to the driven side rotational coupling section. The driven side rotational coupling section is fixed and the position thereof can be corrected slightly, by engaging the driven side rotational coupling section with a drive side rotational coupling section. A transmission gear is provided which meshes with the driven side rotational coupling section and transmits rotational drive force used to move the surface of the developer carrier. By means of an axle provided on at least one end of the transmission gear engaging with a positioning member on the main body of the image forming apparatus, the developer carrier is positioned in the main body of the image forming apparatus.

    摘要： A developer bearing member on which grooves slanting in a thrust direction of the developer bearing member cross other grooves reversely slanting relative to the thrust direction, wherein each of the grooves and the reversely slanting grooves is slanting at an angle of greater than 0° and not greater than 40°. Any two adjacent intersections of the grooves and the reversely slanting grooves in the thrust (or peripheral) direction are preferably on different levels in the peripheral (or thrust) direction. The distance between two adjacent intersections in the thrust direction is preferably from 1.3 mm to 4.8 mm. The distance between two adjacent intersections in the thrust direction is preferably from 0.38 Vd/Vi (mm) to 1.1 Vd/Vi (mm). The deviation in depth of grooves present on a 36° arc surface portion of the member is not greater than 15% of the gap between the image bearing member and the developer bearing member.
