PROBLEM TO BE SOLVED: To provide a developing device that can arrange a developer carrier at a target position relative to a photoreceptor even when support walls are twisted.SOLUTION: A developing device includes a developer carrier 41 that supplies a developer to the surface of a photoreceptor 2, urging members 52 and 53 that urge the developer carrier 41 to the photoreceptor 2 side, and a pair of side wall parts that can be assembled to a pair of support walls supporting both ends in the axial direction of the developer carrier 41 and supporting both ends in the axial direction of the photoreceptor 2, where one of the pair of side wall parts is configured to be assembled to one of the support walls through a hole and a rotation shaft rotatably inserted into the hole, and the other of the pair of side wall parts is configured to be assembled to the other of the support walls through a groove 50e and a rotating moving shaft 40f inserted rotatably and movably inside the groove 50e. |
