摘要： The present invention provides a charging device which can suppress the deterioration of a photosensitive member and the occurrence of an image deletion phenomenon on an electrophotographic image due to an electric discharge product having deposited on a charger shutter, even when having been used for a long period of time. The charging device has an image bearing member which bears an image thereon, a charging member which charges the image bearing member, and a shielding member which shields the charging member from the image bearing member, wherein the shielding member includes a specific material.

摘要： An image forming apparatus includes a plurality of image forming units and a plurality of transfer units. The image forming units have corresponding image carriers and charging units. The image forming units form toner images of different colors on the corresponding image carriers. The transfer units face the corresponding image carriers to form transfer areas between the transfer units and the image carriers, and press a transfer member to the corresponding image carriers to transfer the toner images onto the transfer member at the transfer areas. The charging units include at least one corona-type charger and at least one contact-type charger. The image forming apparatus sets a first transfer condition for the transfer unit(s) corresponding to the image carrier(s) charged by the at least one corona-type charger and a second, separate transfer condition for the transfer unit(s) corresponding to the image carrier(s) charged by the at least one contact-type charger.

摘要： 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.
