ABSTRACT:
A development apparatus includes three developer conveyance paths with separate functions for the supply, recovery and agitation of a developer, respectively, in which a reduction in size of the apparatus can be achieved. An image forming apparatus includes the development apparatus. By a development region width of a supply opening for delivering developer from a downstream end in the direction of conveyance of an agitation conveyance path to an upstream end in the direction of conveyance of a supply conveyance path and a surplus opening for delivering developer from the downstream end in the direction of conveyance of the supply conveyance path to the upstream end in the direction of conveyance of the agitation conveyance path, a space saving of the upper part of the development apparatus can be achieved and a space saving of the development apparatus as a whole can be achieved compared with a conventional development apparatus.
