PROCESS CARTRIDGE AND ELECTROPHOTOGAPHIC IMAGE FORMING APPARATUS - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18212783 Titled 'PROCESS CARTRIDGE AND ELECTROPHOTOGAPHIC IMAGE FORMING APPARATUS'
Simplified Explanation
This abstract describes a process cartridge used in printing or copying machines. The cartridge includes a frame and a photosensitive drum that can rotate. A coupling is connected to the drum to transfer a driving force. The cartridge also has a developing roller and a gear. The gear has teeth, some of which are exposed and face the axis of the drum. The teeth of the gear are shorter than the projection of the coupling in the axial direction of the drum.
Original Abstract Submitted
A process cartridge includes a frame and a photosensitive drum supported by the frame, with the photosensitive drum being rotatable about an axis thereof. A coupling is operatively connected to the photosensitive drum such that a driving force can be transferred from the coupling to the photosensitive drum. A developing roller is supported by the frame, with the developing roller being rotatable about an axis thereof. A gear is positioned at a side of the process cartridge, with the gear being rotatable about an axis thereof. The gear has a plurality of teeth, with at least some of the teeth being exposed teeth that are uncovered by the frame and exposed to outside of the process cartridge, and with a tip of at least one of the exposed teeth facing the axis of the photosensitive drum. As measured in the axial direction of the photosensitive drum, the teeth of the gear are shorter than the projection of the coupling.
