IMAGE FORMING APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240019796 titled 'IMAGE FORMING APPARATUS
Simplified Explanation
The patent application describes an image forming apparatus that includes various components such as a photosensitive member, charging member, exposing device, developing device, transfer member, brush, voltage applying portion, and control portion. The control portion is responsible for controlling the surface potential of the photosensitive member at the brush contacting position.
- The control portion adjusts the surface potential of the photosensitive member in the brush contacting position by changing the contacting position potential difference.
- The contacting position potential difference is defined as the difference between the surface potential of the photosensitive member and the brush voltage.
- The control portion changes the contacting position potential difference from a first potential difference to a second potential difference in a predetermined direction (either increasing or decreasing), and then to a third potential difference in the same predetermined direction.
Potential applications of this technology:
- Image forming apparatus in various industries such as printing, photocopying, and digital imaging.
- Can be used in office environments, commercial printing shops, and manufacturing facilities.
Problems solved by this technology:
- Ensures proper contact between the brush and the photosensitive member, which is crucial for image quality and consistency.
- Allows for precise control of the surface potential of the photosensitive member, resulting in accurate image formation.
- Reduces the risk of image defects caused by improper surface potential control.
Benefits of this technology:
- Improved image quality and consistency.
- Enhanced control over the image forming process.
- Reduced image defects and wastage.
- Increased efficiency and productivity in image forming operations.
Original Abstract Submitted
an image forming apparatus includes a photosensitive member, a charging member, an exposing device, a developing device, a transfer member, a brush, a voltage applying portion, and a control portion controlling a surface potential of the photosensitive member at the brush contacting position. when a value of subtracting a value of the surface potential of the photosensitive member in the brush contacting position from a value of the brush voltage is defined as a contacting position potential difference, the control portion controls the surface potential of the photosensitive member in the brush contacting position so that the contacting position potential difference is changed from a first potential difference to a second potential difference in a predetermined direction which is either one of an increasing direction or a decreasing direction, and then the contacting position potential difference is changed from the second potential difference to a third potential difference in the predetermined direction.
