Abstract:
A charging apparatus including: a first charging roller configured to charge a surface of a photosensitive drum by rotating in contact with the surface of the photosensitive drum; a second charging roller configured to charge the surface of the photosensitive drum by rotating in contact with the surface of the photosensitive drum at a position downstream of the first charging roller in a rotation direction of the photosensitive drum; and a cleaning roller configured to clean a surface of the first charging roller and a surface of the second charging roller by rotating along with rotation of the first and second charging rollers in contact with the surfaces of the first and second charging rollers, an inroad amount of the first charging roller into the cleaning roller being larger than an inroad amount of the second charging roller into the cleaning roller.

Claim (Index 1):
A charging apparatus comprising:\n a first charging roller configured to charge a surface of a photosensitive drum by rotating in contact with the surface of the photosensitive drum; a second charging roller configured to charge the surface of the photosensitive drum by rotating in contact with the surface of the photosensitive drum at a position adjacent to and downstream of a position at which the first charging roller is in contact with the surface of the photosensitive drum with respect to a rotation direction of the photosensitive drum; and a cleaning roller configured to clean a surface of the first charging roller and a surface of the second charging roller by rotating along with rotation of the first charging roller and the second charging roller in contact with the surface of the first charging roller and the surface of the second charging roller, an inroad amount of the first charging roller into the cleaning roller being larger than an inroad amount of the second charging roller into the cleaning roller.
