IMAGE FORMING APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18669028 titled 'IMAGE FORMING APPARATUS
The image forming apparatus described in the patent application includes components such as an image bearing member, a transfer member, an acquiring portion, an applying portion, and a controller.
- The controller adjusts the transfer voltage applied to the transfer member by the applying portion to be substantially constant under constant-voltage control.
- When the toner amount used for a toner image is different, the controller controls the applying portion to change the transfer voltage accordingly.
- The acquiring portion gathers toner amount information for each toner image transferred onto a single recording material.
- Key Features and Innovation:**
- Constant-voltage control of transfer voltage for consistent image quality.
- Dynamic adjustment of transfer voltage based on toner amount for optimal results.
- Accurate acquisition of toner amount information for each transferred image.
- Potential Applications:**
This technology can be applied in various printing and copying machines to improve image quality and consistency.
- Problems Solved:**
This technology addresses issues related to inconsistent image transfer and quality due to varying toner amounts.
- Benefits:**
- Enhanced image quality and consistency.
- Improved overall performance of image forming apparatus.
- Efficient use of toner resources.
- Commercial Applications:**
This technology can be utilized in commercial printing services, office printers, and photocopiers to ensure high-quality output and cost-effective operation.
- Questions about the Technology:**
1. How does the controller adjust the transfer voltage based on toner amount? 2. What are the potential cost savings associated with using this technology in printing machines?
- Frequently Updated Research:**
Ongoing research in this field focuses on further optimizing the transfer voltage control system for even better image quality and efficiency.
Original Abstract Submitted
An image forming apparatus includes an image bearing member, a transfer member, an acquiring portion, an applying portion, and a controller. When a transfer voltage is subjected to constant-voltage control so that the transfer voltage applied to the transfer member by the applying portion is substantially constant, in a case that the transfer voltage, when a toner amount used for a toner image is a first toner amount, is a first voltage, the controller controls the applying portion so that the transfer voltage is a second voltage smaller lower in absolute value than the first voltage in a case that the toner amount is a second toner amount larger greater than the first toner amount. The acquiring portion acquires toner amount information on the toner amount for each toner image transferred onto a single recording material.
