Abstract

A developer circulation system includes a storage tank which stores a developer, a development device, a developer supply passage through which the developer is supplied to the development device from the storage tank, a developer return passage through which the developer is returned to the storage tank from the development device, a circulation pump, and an agitation member which agitates the developer in the storage tank. An outlet of the developer return passage and an opening of the developer supply passage are located in the storage tank, so as to promote a flow of the developer generated by the rotation of the agitation member, at positions furthest from each other along a flow of the developer from the outlet of the developer return passage and the opening of the developer supply passage.
