PROBLEM TO BE SOLVED: To prevent the evil influence (for instance, the generation of an image noise) of the use of a post processing agent. SOLUTION: A brush roller 48 for removing component grains having electric charges having the same polarity as that of the charge of a developer, with the component grains having the polarities different from that of the charge of the developer remaining, in the post processing agent added to the developer is provided between a transferring region 28 and a cleaning region 42. Thus, in this cleaning region 42, an untransferred developer is efficiently recovered and the quantity of the post processing agent passing through the contact part of a blade 40 with a photoreceptor 10, to be carried is decreased so that a noise is never generated in an image formed in an image forming device, to obtain a high-quality image. |
