ELECTROPHOTOGRAPHIC PHOTOSENSITIVE MEMBER, PROCESS CARTRIDGE AND ELECTROPHOTOGRAPHIC APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240118635 titled 'ELECTROPHOTOGRAPHIC PHOTOSENSITIVE MEMBER, PROCESS CARTRIDGE AND ELECTROPHOTOGRAPHIC APPARATUS

Simplified Explanation

The abstract describes an electrophotographic photosensitive member with a protection layer containing a binder resin and particles, meeting specific criteria for thickness and particle diameter.

  • The electrophotographic photosensitive member includes a charge generating layer, a charge transporting layer, and a protection layer.
  • The protection layer contains a binder resin and particles, with specific thickness and particle diameter requirements.
  • The formula in the abstract ensures satisfactory transferability of the photosensitive member.

Potential Applications

This technology could be applied in:

  • Photocopiers
  • Laser printers
  • Scanners

Problems Solved

This innovation addresses issues related to:

  • Transferability of toner onto paper
  • Durability of photosensitive members

Benefits

The benefits of this technology include:

  • Improved image quality
  • Extended lifespan of photosensitive members
  • Consistent performance over time

Potential Commercial Applications

The potential commercial applications of this technology include:

  • Manufacturing of photocopiers
  • Production of laser printers
  • Development of high-quality scanners

Possible Prior Art

One possible prior art could be:

  • Photosensitive members with protection layers containing only binder resin, without particles.

Unanswered Questions

How does the presence of particles in the protection layer affect the overall performance of the electrophotographic photosensitive member?

The abstract mentions the inclusion of particles in the protection layer, but it does not delve into the specific impact of these particles on the functionality of the photosensitive member.

Are there any alternative materials that could be used in the protection layer to achieve similar results?

While the abstract describes the use of a binder resin and particles in the protection layer, it does not explore other potential materials that could be utilized for the same purpose.


Original Abstract Submitted

provided is an electrophotographic photosensitive member that achieves satisfactory transferability. an electrophotographic photosensitive member including a charge generating layer, a charge transporting layer, and a protection layer laminated on a support in the stated order, wherein the protection layer contains a binder resin and particles, and wherein when an average thickness of the protection layer in a site free of the particles is represented by t and a volume-average particle diameter of the particles is represented by dm in a cross-section of the protection layer, the following formula (a) is satisfied.
