FIXING DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240210864 titled 'FIXING DEVICE

The patent application describes a fixing device that includes an endless belt, a rotatable pressing member, a pad member inside the belt, and a sliding member held by the pad member and sliding on an inner circumferential surface of the belt in a nip. The rotatable pressing member nips and feeds a recording material in the nip in cooperation with the belt and fixes a toner image on the recording material by applying heat and pressure. The sliding member includes a base material layer with projections towards the rotatable pressing member and a sliding layer with a curved surface on the outer surface of the projections.

• Endless belt fixing device with rotatable pressing member
• Sliding member with base material layer and sliding layer with curved surface
• Fixing toner image on recording material with heat and pressure
• Projections on sliding member for improved functionality
• Curved surface sliding layer with specific radius of curvature

Potential Applications: - Printing industry for fixing toner images on various materials - Office equipment for high-quality document printing - Manufacturing sector for labeling and packaging applications

Problems Solved: - Ensures efficient and effective fixing of toner images on recording materials - Provides consistent and high-quality results in printing processes

Benefits: - Improved image quality and durability - Increased efficiency in printing operations - Reduced maintenance and downtime for fixing devices

Commercial Applications: Title: Innovative Fixing Device for Printing Industry This technology can be utilized in commercial printers, photocopiers, and multifunction devices to enhance printing quality and efficiency. It can also be integrated into industrial printing systems for large-scale production.

Questions about Fixing Device: 1. How does the curved surface of the sliding layer improve the fixing process? The curved surface of the sliding layer allows for better contact with the recording material, ensuring uniform heat distribution and pressure application for effective fixing of toner images.

2. What are the potential cost savings associated with using this fixing device? By providing consistent and high-quality results, this fixing device can reduce the need for reprints and maintenance, leading to cost savings in the long run.

Original Abstract Submitted

a fixing device includes an endless belt, a rotatable pressing member, a pad member inside of the belt, and a sliding member held by the pad member and sliding on an inner circumferential surface of the belt in a nip. the rotatable pressing member nips and feeds a recording material in the nip in cooperation with the belt and fixes a toner image on the recording material by applying heat and pressure. the sliding member includes a base material layer on which a plurality of projections projecting toward the rotatable pressing member are formed on a side sliding with the belt and a sliding layer provided on an outer surface of the plurality of projections. a shape of a surface of the sliding layer is a curved surface and a radius of curvature r of the curved surface satisfies 300 �m≤r≤850 �m.
