摘要： A developing device includes developing units each including a first gear and a development roller; a rotation supporting member; a cam member having a cam surface surrounding the rotation axis, and being secured to and rotating together with the rotation supporting member; and a driving force transmission member including a cam receiving roller and a second gear. The cam surface includes a curved surface whose curvature is less than a curvature of the cam receiving roller so that, as the first gear approaches a driving position where the first gear receives the driving force from the second gear by the rotation of the cam member, the cam receiving roller is moved away from the rotation axis once, after which the cam receiving roller is moved towards the rotation axis, thereby starting engagement of the first gear with the second gear before the first gear reaches the driving position.

摘要： A developing device includes two developer-transporting members, a container, and four gap retainers. The container contains a developer and rotatably supports rotation shafts of the developer-transporting members using side walls located on both end portions. The gap retainers are supported at end portions of the developer-transporting members and are brought into contact with a subjected-to-development member or a supporter to maintain a gap between the subjected-to-development member and each developer-transporting member. A force with which the two developer-transporting members are pressed toward the subjected-to-development member is applied to the container and all the gap retainers are brought into contact with the subjected-to-development member or the supporter, while axes of rotation of the two developer-transporting members are allowed to become non-parallel with an axis of rotation of the subjected-to-development member.
