ABSTRACT:
It is an object of the present invention to provide a process unit and an image forming apparatus in which generation of loss of image density due to flying off of developer and the edge effect occurring as a side-effect under developing conditions aimed at improving development performance can be reduced, even when a DC bias development system is adopted, and which can suppress developing density unevenness caused by impact occurring on contact of the teeth of gears in the drive system.
