ELECTROPHOTOGRAPHIC PHOTOSENSITIVE MEMBER, PROCESS CARTRIDGE, AND ELECTROPHOTOGRAPHIC APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18463501 titled 'ELECTROPHOTOGRAPHIC PHOTOSENSITIVE MEMBER, PROCESS CARTRIDGE, AND ELECTROPHOTOGRAPHIC APPARATUS
Simplified Explanation
The present disclosure relates to an electrophotographic photosensitive member designed to reduce positive ghosts, as well as a process cartridge and an electrophotographic apparatus incorporating the photosensitive member. The photosensitive member includes a support and a photosensitive layer, with specific compounds included in the photosensitive layer to achieve the desired effect.
- Explanation of the patent/innovation:
- The electrophotographic photosensitive member includes a photosensitive layer with specific compounds to reduce positive ghosts. - The content of one compound in the photosensitive layer is optimized to be 50 to 850 mass ppm relative to another compound. - The design aims to provide high-quality printing with minimal ghosting effects.
- Potential applications of this technology:
- Printers - Photocopiers - Scanners
- Problems solved by this technology:
- Reduced positive ghosts in printed materials - Improved print quality - Enhanced overall performance of electrophotographic devices
- Benefits of this technology:
- Higher quality prints - Enhanced user experience - Increased efficiency in printing processes
- Potential commercial applications of this technology:
- Office equipment manufacturers - Printing companies - Electronics industry
- Possible prior art:
- Previous electrophotographic photosensitive members with different compound compositions - Patents related to reducing ghosting effects in printing processes
Questions:
1. What specific compounds are included in the photosensitive layer to reduce positive ghosts? 2. How does the optimized content ratio of compounds in the photosensitive layer contribute to reducing ghosting effects?
Original Abstract Submitted
An object of the present disclosure is to provide an electrophotographic photosensitive member with suppressed positive ghosts, and a process cartridge and an electrophotographic apparatus each including the electrophotographic photosensitive member. The present disclosure provides an electrophotographic photosensitive member having a support and a photosensitive layer on the support; the photosensitive layer comprises (α) a compound represented by the formula (1), and (β) at least one selected from the group consisting of a compound represented by the formula (2) and a compound represented by the formula (3), wherein a content of the (β) with respect to a content of the (α) is 50 to 850 mass ppm in the photosensitive layer.
