FIXING DEVICE AND IMAGE FORMING APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240241466 titled 'FIXING DEVICE AND IMAGE FORMING APPARATUS
The fixing device described in the patent application includes first and second rotation members, a heater holder with a protrusion, and a heater with a heating element and a substrate.
- The protrusion is located outside the nip portion and on the downstream side in the conveyance direction of a recording material, making contact with the first rotation member.
- The protrusion extends towards the second rotation member in the thickness direction without crossing a nip tangent line, and its length in the longitudinal direction is shorter than the recording material's length.
Potential Applications: - This fixing device can be used in printers, copiers, and other imaging devices to ensure proper fixing of toner or ink on paper. - It can also be applied in industrial settings where heat and pressure are needed for bonding materials together.
Problems Solved: - Ensures efficient fixing of toner or ink on paper without causing damage to the recording material. - Provides consistent heating and pressure for optimal fixing results.
Benefits: - Improved print quality with properly fixed toner or ink. - Extended lifespan of the fixing device due to optimized design. - Reduced maintenance and repair costs for imaging devices.
Commercial Applications: Title: Advanced Fixing Device for Imaging Equipment This technology can be utilized in commercial printers, photocopiers, and industrial printing presses to enhance print quality and efficiency. The market implications include increased productivity and cost savings for businesses that rely on high-quality printing solutions.
Questions about the technology: 1. How does the protrusion on the heater holder improve the fixing process? - The protrusion ensures proper contact between the heater holder and rotation members, leading to consistent heating and pressure for fixing toner or ink on paper.
2. What are the advantages of having a shorter protrusion length compared to the recording material? - A shorter protrusion length prevents interference with the recording material during the fixing process, reducing the risk of damage and ensuring smooth operation.
Original Abstract Submitted
a fixing device includes first and second rotation members, a heater holder having a protrusion, and a heater having a heating element and a substrate having a longitudinal direction and a thickness direction. the protrusion is disposed at a position, which is outside a nip portion and on a downstream side in a conveyance direction of a recording material, and comes into contact with the first rotation member. the protrusion protrudes in the thickness direction toward the second rotation member without crossing a nip tangent line that passes through a contact surface between the first rotation member and the second rotation member and extends parallel to the contact surface, and a length in the longitudinal direction of the protrusion is shorter than a length in the longitudinal direction of the recording material of a maximum size which is able to be conveyed.
