DEVELOPING APPARATUS, PROCESS CARTRIDGE, AND IMAGE-FORMING APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240288793 titled 'DEVELOPING APPARATUS, PROCESS CARTRIDGE, AND IMAGE-FORMING APPARATUS

The abstract of the patent application describes a contact member with a volume resistivity of 10ohm⋅cm or less that comes into contact with a surface of a developer carrier. The developer must meet specific conditions, including having a resistance value of 1.0×10ohms or less between a rotating member and the contact member.

• The contact member must have a volume resistivity of 10ohm⋅cm or less.
• The rotating member and contact member must have a resistance value of 1.0×10ohms or less.
• The developer must have a first resistance value ranging from 1.0×10ohms to 1.0×10ohms when the rotating member is stopped.
• The second resistance value must be in the range of the first resistance value and be at least 40% higher when the rotating member is rotated at 200 mm/s.

Potential Applications: - This technology could be used in printers, copiers, and other imaging devices. - It may also have applications in industrial machinery that require precise contact members.

Problems Solved: - Ensures proper contact between the rotating member and the developer. - Maintains consistent resistance values for efficient operation.

Benefits: - Improved performance and reliability in imaging devices. - Enhanced durability and longevity of the contact member.

Commercial Applications: Title: Advanced Contact Member Technology for Imaging Devices This technology could be commercialized by manufacturers of printers, copiers, and other imaging devices looking to enhance the performance and reliability of their products.

Questions about the technology: 1. How does the contact member's volume resistivity impact the performance of the developer carrier? 2. What are the specific benefits of having a resistance value of 1.0×10ohms or less between the rotating member and the contact member?

Original Abstract Submitted

a contact member that comes into contact with a surface of a developer carrier has a volume resistivity of 10ohm�cm or less, and a developer satisfies the following conditions: a rotating member and the contact member have a resistance value of 1.0�10ohms or less, and a first resistance value ranges from 1.0�10ohms to 1.0�10ohms as measured in a state where the rotating member is stopped and the developer is located between the rotating member and the contact member, and a second resistance value is in the range of the first resistance value and is 40% or more with respect to the first resistance value, as measured in a state where the rotating member is rotated at 200 mm/s with respect to the contact member and the developer is located between the rotating member and the contact member.
