Developing apparatus and image forming apparatus having the same
 A toner bearing body unit is constituted as one assembled unit including a toner bearing body for holding toners supplied from a toner supply roller of a housing main body at an outer peripheral surface thereof, a toner layer thickness regulating member for electrically charging the toners by applying pressure toward the outer peripheral surface of the toner bearing body and for forming a toner thin layer on the toner bearing body, and a holding member for holding the toner bearing body and the toner layer thickness regulating member. The toner bearing body unit is constituted to be directly attachable to and detachable from an outer side of the housing main body of a developing apparatus. Accordingly, an uniform toner thin layer having a predetermined thickness can be formed stably on the toner bearing body during a long period of use, and the developing apparatus reconstructed so that replacement of the components thereof can be carried out easily. Further a developing apparatus having a good recycling performance can be provided.
