IMAGE FORMING APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240302785 titled 'IMAGE FORMING APPARATUS
The patent application describes an image forming apparatus with a unique brush configuration for collecting developer remaining on the surface of the image bearing member.
- The apparatus includes an image bearing member, a charging member, a developing roller, a transfer roller, and a brush.
- The brush is positioned downstream of the transfer portion and upstream of the charging portion in the rotation direction of the image bearing member.
- After transferring a developer image onto a transferred member, the brush collects the remaining developer on the image bearing member's surface.
- The brush's contact region with the image bearing member overlaps a virtual line containing the rotation axis of the image bearing member.
Potential Applications: - Printers - Photocopiers - Scanners
Problems Solved: - Efficient collection of remaining developer - Improved image quality - Reduced maintenance needs
Benefits: - Enhanced image reproduction - Extended lifespan of components - Cost-effective operation
Commercial Applications: Title: Innovative Image Forming Apparatus for Enhanced Printing Quality This technology can be used in various commercial printing devices to improve image quality and reduce maintenance costs.
Questions about the technology: 1. How does the brush configuration improve the efficiency of developer collection? 2. What are the potential cost savings associated with using this image forming apparatus?
Original Abstract Submitted
an image forming apparatus including an image bearing member, a charging member, a developing roller, a transfer roller, and a brush configured to be brought into contact with a surface of the image bearing member on a side downstream of a transfer portion and upstream of a charging portion in a rotation direction of the image bearing member and in which, wherein, after the transfer of a developer image onto a transferred member, a developer remaining on the surface of the image bearing member is collected by the developing roller, the brush is disposed such that, in a cross section perpendicular to a rotation axis of the image bearing member, a contact region of the surface of the image bearing member in contact with the brush overlaps a virtual line containing the rotation axis of the image bearing member and extending upward from the rotation axis in a vertical direction.
