Abstract
A developing apparatus includes a developer bearing member, a supporting portion, an urging unit, and a movement regulating member. The developer bearing member rotates while bearing developer. The supporting portion rotatably and movably supports the developer bearing member and includes a recessed portion that is formed into a concave shape. The urging unit urges the developer bearing member in a predetermined direction of the rotational axis direction. The movement regulating member is fitted to an end of the developer bearing member and is movable together with the developer bearing member. The movement regulating member may move to a first position where movement in a perpendicular direction is regulated by coming into contact with a portion of the supporting portion and a second position that is a position apart from the first position and movable in the perpendicular direction without coming into contact with the portion of the supporting portion.
