==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.
