PROBLEM TO BE SOLVED: To supply a sufficient amount of developer to a developer carrier and improve image quality. SOLUTION: The development apparatus includes: a developer carrier for developing an electrostatic latent image formed on an image carrier; a first developer supply member whose surface is formed from a foamed body and supplies developer to the developer carrier; and a second developer supply member which is disposed near the first developer supply member and opposite the upper face of the first developer supply member, and periodically moves to supply the developer to the first developer supply member. A distance between the first and second developer supply members in the position where the second developer supply member is located near to the first developer supply member is 0.8 (mm) or less. In the case, the developer is moved onto the surface of the first developer supply member as the second developer supply member periodically moves. Accordingly, the developer can sufficiently be supplied to the developer carrier. COPYRIGHT: (C)2005,JPO&NCIPI |
