PROCESS CARTRIDGE AND IMAGE FORMING APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240210875 titled 'PROCESS CARTRIDGE AND IMAGE FORMING APPARATUS
The patent application describes a process cartridge for a printing device, which includes a photosensitive drum, a developing roller, a developer supplying roller, a driving force receiving portion, a first driving force transmitting portion, a second driving force transmitting portion, and flexible sheets.
- The process cartridge includes a photosensitive drum and a developing roller for printing.
- A developer supplying roller is in contact with the developing roller to supply developer material.
- A driving force receiving portion is located at the end of the supplying roller shaft.
- The cartridge has a first and second driving force transmitting portion for efficient operation.
- Flexible sheets are used to intermittently contact the second portion with rotation, enhancing performance.
- The roller rotates in the opposite direction to the drum, with a higher peripheral speed for optimal printing quality.
Potential Applications: - This technology can be used in laser printers, photocopiers, and multifunction devices. - It can improve printing quality and efficiency in various office and commercial settings.
Problems Solved: - Enhances the development and transfer of toner onto the photosensitive drum. - Increases the overall performance and longevity of the printing process.
Benefits: - Improved printing quality and consistency. - Enhanced efficiency and reliability in printing operations. - Cost-effective solution for printing needs in various industries.
Commercial Applications: - This technology can be applied in the manufacturing of printing devices for businesses, schools, and government agencies. - It can also be used in the production of aftermarket printing supplies for a wide range of printers.
Questions about the technology: 1. How does the flexible sheet mechanism improve the performance of the process cartridge? - The flexible sheets help ensure consistent contact between the driving force transmitting portions, leading to more efficient operation.
2. What are the main advantages of having a developer supplying roller in contact with the developing roller? - The developer supplying roller ensures a steady and reliable supply of developer material to the developing roller, resulting in consistent print quality.
Original Abstract Submitted
a process cartridge includes a photosensitive drum; a developing roller; a developer supplying roller, provided in contact with the developing roller; a driving force receiving portion provided at a shaft end of the supplying roller; a first driving force transmitting portion; a second driving force transmitting portion; flexible sheets provided adjacent to an engaging portion between the first portion and the second portion to intermittently contact the second portion with rotation of the second portion, wherein a rotational direction of the roller is opposite to that of the roller, and a peripheral speed of the roller is larger than that of the roller.
