<P>PROBLEM TO BE SOLVED: To provide a development apparatus, capable of obtaining a stable image free from uneven image density by reducing the lowering of the image density at the axial end part of a developer carrier, and to provide an image forming apparatus and a process cartridge which uses the development apparatus. <P>SOLUTION: The development apparatus is provided with a toner-block preventing member 22 for vibrating developer lying in the contacting area, where the developer 12 checked by a 2nd control member 15 and the toner 17 in a toner storing part 18 is in contact with each other and preventing toner-blocking. Thus, even if the developer is deviated to the axial end part of the developing sleeve 11, the toner is prevented from being blocked, and then the lowering of the image density due to insufficient toner supply can be prevented. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
