Abstract
A charging device is configured to apply electric charge to an image carrier provided outside the charging device. The charging device includes: a cored bar member; and a conductive resin layer provided on a surface of the cored bar member. The conductive resin layer has a film thickness of 200 μm or less. Filtered maximum waviness in an axial direction of the cored bar member is 8 μm or less in a range of a reference length of 60 mm.
