Abstract
A charging module for applying a uniform electrostatic charge to a charge retentive surface is provided. The charging module is operably electrically connectable to a power supply for supplying an electrical bias to the charging apparatus. The charging module is mountable into a process cartridge. The process cartridge includes a cartridge mounting surface for cooperation with the charging apparatus. The apparatus includes a housing including a housing mounting feature and an electrode. The electrode is mounted to the housing and is positioned adjacent the surface in a non-contact relationship therewith. The housing mounting feature is adapted to be cooperable with the cartridge mounting surface to secure the placement of the charging module into the cartridge without the need for any installation tools.
