<P>PROBLEM TO BE SOLVED: To provide a developer conveying device which can reduce cost, and has high image productivity and also has excellent high image quality maintainability by improving the conveying precision of developer, and further is simple in configuration, and to provide an image forming apparatus provided with the developer conveying device. <P>SOLUTION: The developer conveying device is configured to control replenishment control, so that the control time is successively increased at a rear end reference in maximum supply amount control. Thus, a developer liquefaction state in a developer conveying pipe occurring due to vibration after a movement type developing unit is moved is avoided as much as possible. <P>COPYRIGHT: (C)2007,JPO&INPIT |
