PROCESS CARTRIDGE AND IMAGE FORMING APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 17965055 titled 'PROCESS CARTRIDGE AND IMAGE FORMING APPARATUS
Simplified Explanation
The patent application describes a process cartridge for an image forming apparatus, which includes a photosensitive drum unit and a developing unit. The photosensitive drum unit has positioning portions to position it relative to the main assembly, while the developing unit is connected to the photosensitive drum unit and includes a developing roller and a storing means with a contact surface for electrical connection with the main assembly.
- The first and second positioning portions of the photosensitive drum unit ensure proper alignment with the main assembly.
- The contact surface of the storing means allows for communication between the developing unit and the main assembly.
- The first line segment connecting the positioning portions and the first linear line passing through the contact surface intersect each other in the axial direction of the photosensitive drum.
Potential applications of this technology:
- Image forming apparatus such as printers, copiers, or multifunction devices.
- Any application requiring precise positioning and communication between components.
Problems solved by this technology:
- Ensures accurate positioning of the photosensitive drum unit relative to the main assembly.
- Facilitates effective communication between the developing unit and the main assembly.
Benefits of this technology:
- Simplifies the process of mounting the process cartridge to the main assembly.
- Improves the overall performance and reliability of the image forming apparatus.
- Enhances the quality and consistency of the printed or copied output.
Original Abstract Submitted
A process cartridge detachably mountable to a main assembly of an image forming apparatus, the process cartridge includes a photosensitive drum unit including a photosensitive drum, and a first and second positioning portions Configured to position the photosensitive drum unit relative to the main assembly; and a developing unit connected with the photosensitive drum unit, the developing unit including a developing roller, a storing means having a contact surface electrically connectable with a main assembly contact of the main assembly to communicate with the main assembly. As seen in an axial direction of the photosensitive drum, a first line segment connecting the first positioning portion and the second positioning portion with each other and a first linear line passing through the contact surface and perpendicular to the contact surface crosses with each other.
