Charging device, imaging cartridge and image forming apparatus having charging device

摘要

A charging device which includes a grid that has a curvature surface placed to face an outer circumferential surface of a photoconductive drum; a carrying member that carries the grid in a portion having a curvature to form the curvature surface of the grid; and position adjusting mechanisms that moves a position of the carrying member to adjust a position of the grid in a sub-scanning direction of the photoconductive drum, an imaging cartridge and an image forming apparatus having the same.

主权项

1. A charging device for use with a photoconductive drum, the charging device comprising:
a grid that has a curvature surface curved in a sub-scanning direction of the photoconductive drum and placed to face an outer circumferential surface of the photoconductive drum; a carrying member that carries said grid in a portion having a curvature to form said curvature surface of said grid; a position adjusting mechanism that moves a position of said carrying member to adjust a position of said grid in the sub-scanning direction of said photoconductive drum; a supporting member that supports both ends of said grid; and an auxiliary carrying member whose curvature of the portion carrying said grid is greater than the curvature of said carrying member, between said carrying member and said supporting member.
