IMAGE FORMING APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240103396 titled 'IMAGE FORMING APPARATUS
Simplified Explanation
The image forming apparatus described in the patent application includes a controller that controls the potential difference between a supplying member and a developing member during image forming operations. The controller switches between a first operation with a potential difference in one direction and a second operation with a potential difference in the opposite direction based on the presence or absence of a recording material in the conveyance passage.
- The controller controls the potential difference between the supplying member and the developing member to manipulate the toner charged to a normal polarity.
- The switching between the first and second operations is based on information about the recording material in the conveyance passage.
Potential Applications
This technology could be applied in various types of image forming devices such as printers, copiers, and multifunction devices.
Problems Solved
This technology helps in improving the image quality and efficiency of image forming operations by optimizing the potential difference between the supplying member and the developing member.
Benefits
The benefits of this technology include enhanced image quality, reduced toner consumption, and improved overall performance of the image forming apparatus.
Potential Commercial Applications
This technology could be utilized in the manufacturing of commercial printers, copiers, and other imaging devices to enhance their functionality and performance.
Possible Prior Art
One possible prior art could be the use of controllers to regulate potential differences in image forming devices, but the specific method described in this patent application may be unique.
Unanswered Questions
How does this technology compare to existing methods of controlling potential differences in image forming devices?
This article does not provide a direct comparison with existing methods, so it is unclear how this technology differs or improves upon current practices.
What impact could this technology have on the overall efficiency and cost-effectiveness of image forming operations?
While the benefits of the technology are mentioned, the specific impact on efficiency and cost-effectiveness is not detailed in the article.
Original Abstract Submitted
an image forming apparatus includes a controller. the controller controls to perform a first operation in which a first potential difference is formed between a supplying member and a developing member, the first potential difference being a potential difference in a direction in which an electrostatic force in a first direction toward the developing member from the supplying member is acted on toner charged to a normal polarity, and a second operation in which a second potential difference is formed between them and in a second direction opposite to the first direction. when an image forming operation is performed, the controller controls timing for changing from the first operation to the second operation based on information on presence or absence of a recording material in a conveyance passage toward a transferring portion in a non-image forming operation before the recording material is nipped and conveyed at the transferring portion.
