摘要： A developing unit includes a developer carrying member, a supplying compartment, a recovery compartment, and an agitation compartment. The developer carrying member develops a latent image formed on an image carrier with a two-component developer. The supplying compartment has a developer supplying transporter to supply the two-component developer to the developer carrying member while transporting the two-component developer. The recovery compartment has a developer recovery transporter to transport the two-component developer recovered from the developer carrying member. The agitation compartment has a developer agitation transporter to agitatingly transports developer. The developer agitation transporter includes a first screw having a screw pitch to transport developer to an upstream end of the supplying compartment from a downstream end of the agitation compartment. The developer supplying transporter includes a second screw having a given screw pitch, which is greater than a screw pitch of the first screw.

摘要： An image forming apparatus includes a process cartridge, a toner storage, and a toner supplying unit. The process cartridge includes an image bearing member, a developer container, a developer bearing member, and a pair of side plates. The developer container includes a toner inlet mounted at a predetermined position on one of its top surface. The pair of side plates are arranged in parallel and separated by a predetermined distance which determines a predetermined longitudinal width of the process cartridge and configured to support the components in the process cartridge.

摘要： A development apparatus comprises three developer conveyance paths with separate functions for the supply, recovery and agitation of a developer, in which a reduction in size of the apparatus can be achieved. An image forming apparatus comprises the development apparatus. By provision in a development region width α of a supply opening for delivering developer from the downstream end in the direction of conveyance of an agitation conveyance path to the 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.
