IMAGE FORMING APPARATUS THAT CONTROLS SHEET INTERVAL - A simplified explanation of the abstract
This abstract first appeared for US patent application 18628530 titled 'IMAGE FORMING APPARATUS THAT CONTROLS SHEET INTERVAL
The image forming apparatus described in the patent application includes a conveyance member, an image forming unit, a fixing device, a component, and a controller.
- The image forming unit creates a toner image on a conveyed sheet.
- The fixing device fixes the toner image onto the sheet, with heat propagating to the component.
- The controller manages the passing sheet interval between multiple sheets passing through the fixing device.
- Throughput control is executed to regulate the sheet interval, ensuring the temperature of a non-passage region and the component are maintained below specific limit temperatures.
Potential Applications: - This technology can be applied in various printing devices such as photocopiers, printers, and multifunctional devices. - It can also be used in industrial printing processes where high-quality images need to be produced efficiently.
Problems Solved: - Ensures consistent and reliable fixing of toner images onto sheets. - Prevents overheating of components, which can lead to malfunctions and reduce the lifespan of the apparatus.
Benefits: - Improved image quality and durability of printed materials. - Enhanced efficiency and performance of the image forming apparatus. - Reduced maintenance and repair costs due to optimized temperature control.
Commercial Applications: - This technology can be utilized in office settings, print shops, and commercial printing businesses to enhance productivity and output quality.
Questions about the Technology: 1. How does the controller manage the passing sheet interval to control temperature levels effectively? 2. What are the specific components within the image forming apparatus that are responsible for heat propagation and temperature regulation?

Original Abstract Submitted
An image forming apparatus includes a conveyance member to convey a sheet, an image forming unit, a fixing device, a component, and a controller. The image forming unit forms a toner image on the conveyed sheet conveyed. The fixing device fixes an unfixed toner image formed on the sheet, onto the sheet. Heat of the fixing device propagates to the component. The controller controls a passing sheet interval between a plurality of sheets passing through the fixing device. The controller executes throughput control for controlling a sheet interval, which is an interval between a preceding sheet and a subsequent sheet passing through the fixing device, such that a temperature of a non-passage region through which sheets do not pass in the fixing device is suppressed to a predetermined first limit temperature or less and a temperature of the component is suppressed to a predetermined second limit temperature or less.
