Abstract
A stirrer roller of a developing device for electrophotography has elliptical plates obliquely attached to an axis such that they are mutually parallel and their projections in the directions of the axis are circular. Each plate has notches or holes symmetrically positioned with respect to the center such that the trajectories of these notches do not overlap when the roller rotates around its axis.
