PROCESS CARTRIDGE AND ELECTROPHOTOGRAPHIC IMAGE FORMING APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240295851 titled 'PROCESS CARTRIDGE AND ELECTROPHOTOGRAPHIC IMAGE FORMING APPARATUS

The abstract of the patent application describes a process cartridge with a frame, a photosensitive drum, a projection, and a gear, all positioned at the side of the process cartridge.

The frame of the process cartridge has a side surface and supports a rotatable photosensitive drum.
The photosensitive drum has a first end at the side of the process cartridge and a second end opposite to the first end.
A projection coaxial with the photosensitive drum is positioned at the side of the process cartridge, with at least a tip of the projection exposed outside the cartridge.
A gear with exposed teeth is also positioned at the side of the process cartridge, with at least one tip of the teeth facing the axis of the photosensitive drum.

Potential Applications: - This technology can be used in printers, copiers, and other imaging devices that require a process cartridge. - It can improve the efficiency and functionality of printing and copying processes.

Problems Solved: - The technology provides a stable and reliable mechanism for supporting and rotating the photosensitive drum. - It ensures proper alignment and operation of the gear teeth for smooth printing and copying.

Benefits: - Enhanced performance and durability of process cartridges. - Improved print quality and consistency. - Simplified maintenance and replacement of components.
