FIXING DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18599949 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 on the outer surface of the projections with a curved surface.

• Endless belt fixing device with rotatable pressing member
• Sliding member with base material layer and sliding layer
• Curved surface sliding layer with specific radius of curvature
• Heat and pressure used to fix toner image on recording material
• Efficient and precise fixing process

Potential Applications: - Printing industry for high-quality image fixing - Office equipment for document printing - Manufacturing sector for labeling and packaging

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 μm≤R≤850 μm.
