IMAGE FORMING APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18339008 titled 'IMAGE FORMING APPARATUS
Simplified Explanation
The patent application describes an image forming apparatus that includes an image bearing member, an intermediate transfer belt, power sources, and a control unit. The control unit controls the discharge current supplied to the intermediate transfer belt based on the detection results of the power sources.
- The image forming apparatus includes an image bearing member, an intermediate transfer belt, power sources, and a control unit.
- The control unit controls the discharge current supplied to the intermediate transfer belt based on the detection results of the power sources.
- The control unit ensures constant current control of the discharge current during print job execution.
- When changing from one discharge current to another, the control unit controls the power source to ensure that the intermediate transfer belt trailing edge and leading edge pass through the primary transfer portion at the appropriate times.
Potential applications of this technology:
- Image forming apparatus in printing machines
- Photocopiers
- Scanners
Problems solved by this technology:
- Ensures constant current control of the discharge current during print job execution
- Ensures proper timing of the intermediate transfer belt edges passing through the primary transfer portion
Benefits of this technology:
- Consistent and accurate image transfer during printing
- Improved print quality
- Efficient use of power sources
Original Abstract Submitted
An image forming apparatus includes an image bearing member, an intermediate transfer belt, first, second, and third power sources, and a control unit. During print job execution, the control unit controls the third power source such that a discharge current supplied to the intermediate transfer belt is constant current controlled based on first and second power source current supply detection results. When changing from a first to a second discharge current, the control unit controls the third power source such that, after a first image forming region passes through a primary transfer portion, an intermediate transfer belt trailing edge to which the first discharge current is supplied initially passes through the primary transfer portion and such that, before a second image forming region passes through the primary transfer portion, an intermediate transfer belt leading edge to which the second discharge current is supplied initially passes through the primary transfer portion.
