Corona charging device cleaning apparatus and method of cleaning a corona charging device

A method of cleaning a corona charging device, the method comprising:

• providing a side shield cleaning member attached to two oppositely-facing side surfaces of a support member to clean an inner surface of a side shield of the corona charging device, a screen grid cleaning member attached to a surface of a concavity of the support member to clean a screen grid of the corona charging device, and a charging-component cleaning member disposed inside a cavity portion of the support member to clean a charging component of the corona charging device, wherein
• the side shield cleaning member includes an abrasive material that is more abrasive that the screen grid cleaning member and the charging-component cleaning member;
• and
• moving the side shield cleaning member substantially along a length of the corona charging device to remove particles from the inner surface of the side shield.

A corona charging device cleaning apparatus comprising:

• a support member including two side surfaces that face in opposite directions away from each other, a concavity, and a cavity portion;
• a side shield cleaning member attached to the side surfaces to clean an inner surface of a side shield of a corona charging device;
• a screen grid cleaning member attached to the concavity of the support member to clean a screen grid of the corona charging device;
• and
• a charging-component cleaning member disposed inside the cavity portion of the support member to clean a charging component of the corona charging device, wherein
• the side shield cleaning member includes an abrasive material that is more abrasive than the screen grid cleaning member and the charging-component cleaning member.
