<p>A photoconductive drum unit 50 includes a frame 51, a photoconductive drum 5, and a scorotron charging unit 6. The charging unit includes a pair of mounting members 61, 62, a discharging electrode filament 63, a shield casing 64, a grid 65, and a combining member 60. The mounting members are mounted and fixed at both end portions of the frame. The discharging electrode filament is laid across under a tensioned state between the mounting members. The shield casing is supported by being combined between the mounting members, and covers the discharging electrode filament. The grid is laid across under a tensioned state between the mounting members and arranged in an opening of the shield casing. The combining member combines the mounting members and the shield casing under a state in which a slight displacement is permitted between the mounting members and the shield casing.</p> |
