More Information
Summary:Methods and apparatus for increasing the bias force between a developer half and a cleaner half of a process cartridge are disclosed. One or more springs are interposed between the cleaner half and the developer half of the process cartridge. These springs are of sufficient strength to maintain a constant separation between the developer and the photosensitive member of the process cartridge. Sources of force other than springs, such as weights or elastic members may also be employed to provide and increase the bias force urging the developer and photosensitive member together.
