Abstract
A development device includes a developer carrier, a restriction member to control a layer thickness of the developer on the developer carrier, first and second developer supply members being in contact with the developer carrier. Each of the developer supply members is configured to rotate at a speed having a constant ratio to a rotation speed of the developer carrier. The second developer supply member and the restriction member are arranged in this order downstream of the first developer supply member in a rotating direction of the developer carrier. A peripheral speed (a speed of the outer peripheral surface) of the second developer supply member is set to be slower than that of the first developer supply member.
