In a development apparatus of the present invention, a guide member is provided which extends through the toner receiving opening located above the agitation/transfer device to surround the pathway of the toner falling from the toner container to guide the same to the agitation/transfer device, the guide member is formed to be broaden toward the agitation/transfer device, and the bottom edge part of the guide member facing the agitation/transfer device is shaped to run along the rotational circumference of the agitation/transfer device, so that the piling up of toner between the agitation/transfer device and inner wall of the developing apparatus is prevented.
