<P>PROBLEM TO BE SOLVED: To solve the problem in an image forming device that uses a two-component developer, wherein processing cartridges are commonly used even in a small developing unit for agitating the toner with magnetic carriers to statically charge the toner insufficiently resulting in the stained surface of the transfer paper, then conventionally for this reason the toner is statically charged by the friction in the developer near the developer regulating blade receiving a large load to the toner in the developer reservoir thus degrading the developer. <P>SOLUTION: Agitating screws 66, 67 are provided respectively in the agitating chamber 86, close to the toner replenishing hole and in the agitating chamber 87 close to the developing sleeve 68. The two-component developer circulates through both agitating chambers, connected to each other at their ends. The developer is compressed and quickly static charged, by providing a stagnation path to delay its flow, during the time it is making a single round in the developer container 1. <P>COPYRIGHT: (C)2007,JPO&INPIT |
