Abstract
This invention is to provide a developing device uniformly developing an image along an axis line of a developing roller and stably obtaining the image with a uniform concentration. The developing device comprises: a developer tank, the developing roller, and a cylindrical layer thickness-regulating member. The layer thickness-regulating member comprises a body part regulating a layer thickness of a developer retained on an outer periphery of the developing roller; a first supporting part having a diameter smaller than that of the body part and supporting the body part at one end of the body part; and a second supporting part having a diameter smaller than or the same as that of the body part and supporting the body part at the other end of the body part. The first supporting part is provided such that a central axis of the first supporting part is configured to be eccentric to a central axis of the body part at a predetermined eccentricity ratio; therefore, the body part tentatively supported by the first supporting part and the second supporting part is appropriately rotated and adjusted to obtain a predetermined gap before the layer thickness-regulating member is fixedly supported by the developer tank.
