IMAGE FORMING APPARATUS FOR FORMING IMAGES ON SHEETS BY USING TONER - A simplified explanation of the abstract
This abstract first appeared for US patent application 17979934 titled 'IMAGE FORMING APPARATUS FOR FORMING IMAGES ON SHEETS BY USING TONER
Simplified Explanation
The abstract describes an image forming apparatus that reduces density unevenness in printed images by modulating the DC component of a developing voltage. It also aims to reduce fogging of toner on non-exposure regions and adhesion of carrier to the photosensitive member.
- The image forming apparatus controls a generation circuit to modulate the DC component of a developing voltage.
- The modulation is based on a first correction component to reduce density unevenness in printed images.
- The first correction component is restricted to minimize fogging of toner on non-exposure regions.
- The first correction component is also restricted to reduce adhesion of carrier to the photosensitive member.
- The apparatus aims to improve print quality by reducing density unevenness, fogging, and adhesion issues.
Potential Applications
This technology can be applied in various image forming devices, such as printers, copiers, and multifunctional devices used in offices, homes, and commercial settings.
Problems Solved
1. Density unevenness in printed images: The technology addresses the issue of inconsistent density across printed images, resulting in poor print quality. 2. Fogging of toner on non-exposure regions: By restricting the first correction component, the technology reduces the occurrence of toner fogging on areas not exposed by the exposure unit. 3. Adhesion of carrier to the photosensitive member: The technology also minimizes the adhesion of carrier particles to the photosensitive member, which can cause print defects and damage to the device.
Benefits
1. Improved print quality: By reducing density unevenness, the technology enhances the overall quality and clarity of printed images. 2. Reduced toner fogging: Restricting the first correction component helps prevent toner fogging on non-exposure regions, resulting in cleaner prints. 3. Minimized adhesion issues: By reducing carrier adhesion to the photosensitive member, the technology helps maintain the longevity and performance of the image forming apparatus.
Original Abstract Submitted
An image forming apparatus is configured to control a generation circuit to modulate a DC component of a developing voltage based on a first correction component such that a density unevenness is reduced. The image forming apparatus is further configured to restrict the first correction component for modulating the DC component of the developing voltage such that fogging of toner that may occur on a non-exposure region which is not exposed by an exposure unit and adhesion to a photosensitive member of carrier included in a developer are reduced.
