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

This abstract first appeared for US patent application 20240219861 titled 'ELECTROPHOTOGRAPHIC BELT AND ELECTROPHOTOGRAPHIC IMAGE FORMING APPARATUS

The abstract describes an electrophotographic belt with a cylindrical film as a base layer, consisting of a crystalline polyester, an amorphous polyester, and carbon black.

• The content ratio of carbon black in the cylindrical film is 2.0% by mass or more.
• The average alignment degree and angle of the carbon black in the circumferential direction of the film are 0.30 or more and -10° to +10°, respectively.
• The cylindrical film has a first phase with the amorphous polyester and carbon black, and a second phase with the crystalline polyester and a (meth)acrylic resin.
• The (meth)acrylic resin has a specific structure represented by formula (a) in the patent application.

Potential Applications: - This technology can be used in electrophotographic printing processes. - It may find applications in photocopiers, laser printers, and other imaging devices.

Problems Solved: - Improved durability and performance of electrophotographic belts. - Enhanced image quality and resolution in printing applications.

Benefits: - Increased longevity of electrophotographic belts. - Higher quality and more precise printing results. - Reduced maintenance and replacement costs for printing equipment.

Commercial Applications: Title: Advanced Electrophotographic Belt Technology for Printing Applications This technology can be utilized by manufacturers of printing equipment to enhance the performance and longevity of their products, leading to improved customer satisfaction and potentially higher market share in the printing industry.

Questions about Electrophotographic Belt Technology: 1. How does the inclusion of carbon black in the cylindrical film impact the performance of the electrophotographic belt? - The carbon black helps improve the alignment and conductivity of the film, leading to better printing results.

2. What role does the (meth)acrylic resin play in the second phase of the cylindrical film? - The (meth)acrylic resin enhances the mechanical properties and durability of the film, contributing to its overall performance in printing applications.
