<P>PROBLEM TO BE SOLVED: To provide a development device capable of adjusting developer around a developing roll, using a simple constitution. <P>SOLUTION: The development device 40 includes the developing roll 60; a developing chamber 70, in which the developing roll is disposed; a restricting member 68 for temporarily restricting the supply of fresh developer to the developing roll 60; a developer storage chamber 62 separated from the developing chamber 70 by the restricting member 68 and having capacity greater than the developing chamber 70; and a stir conveyance member 64, disposed in the developer storage chamber 62 and used for conveying the developer, while stirring it. By the use of a stir conveyance member drive gear for driving the stir conveyance member 64, a follower gear disposed opposite the stir conveyance member drive gear, and a drive gear disposed opposite the follower gear and adapted to drive the restricting member 68, the restricting member 68 intermittently rotates, in synchronization with the stir conveyance member 64 and stops so as to separate the developer storage chamber 62 and the developing chamber 70 from each other. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
