Abstract
A developing device includes a main body that is arranged between a pair of supporting members and includes a developing roller. Both end portions of the developing roller are supported by the supporting members in a first direction in which the developing roller is movable toward and away from an image carrier. A groove is formed on each of the supporting members. Either one of an end portion of the developing roller and a bearing that supports the end portion is inserted into the groove. Either one of at least one of the end portions of the developing roller and at least one of the bearings is movable in the groove in a second direction that intersects the first direction.
