Abstract:
A charging device includes a first charging unit and a second charging unit. The first charging unit electrostatically charges a surface of an image bearing member that comes into contact with a medium onto which an image is to be ultimately transferred. The first charging unit is disposed in correspondence with an entire region of the image bearing member in a first scanning direction. The second charging unit is disposed in an overlapping region where a non-passing region of a small-width medium and a passing region of a maximum-usable-width medium overlap when viewed in the first scanning direction. The small-width medium has a width smaller than a maximum usable width of the maximum-usable-width medium. The second charging unit electrostatically charges the overlapping region.

Claim (Index 9):
A charging device comprising:\n first charging means that electrostatically charges a surface of an image bearing member that comes into contact with a medium onto which an image is to be ultimately transferred, the first charging means being disposed in correspondence with an entire region of the image bearing member in a first scanning direction; and second charging means disposed in correspondence with an overlapping region where a non-passing region of a small-width medium and a passing region of a maximum-usable-width medium overlap when viewed in the first scanning direction, the small-width medium having a width smaller than a maximum usable width of the maximum-usable-width medium, the second charging means electrostatically charging the overlapping region, wherein a bias to be applied by the second charging means is increased each time an accumulative number of prints of the small-width medium increases wherein the second charging unit has a cover that is disposed in the mid region of the second charging unit in the first scanning direction and is connected to ground.
