IMAGE FORMING APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18520798 titled 'IMAGE FORMING APPARATUS
The abstract describes an image forming apparatus with a developing roller that can be in contact with a photosensitive drum or separated from it. The apparatus includes components to acquire and correct information on the rotation amount of the developing roller in different positions, and a notifying portion to inform about the lifetime of the developing roller based on the corrected information.
- Moving unit to move the developing roller
- Driving portion to rotate the developing roller in contact or separated positions
- Acquiring portion to correct rotation amount information using correction coefficients
- Notifying portion to inform about the developing roller's lifetime based on corrected information
Potential Applications: - Printing industry for high-quality image formation - Office equipment for efficient document processing
Problems Solved: - Ensures accurate rotation information for optimal image quality - Extends the lifetime of the developing roller
Benefits: - Improved image quality - Extended lifespan of equipment - Enhanced efficiency in printing processes
Commercial Applications: Title: Advanced Image Forming Technology for Enhanced Printing This technology can be utilized in commercial printers, copiers, and multifunction devices to improve image quality, extend equipment lifespan, and enhance overall efficiency in document processing.
Questions about the technology: 1. How does the acquiring portion correct rotation information for the developing roller? - The acquiring portion corrects rotation information using specific correction coefficients for contact and separated positions. 2. What are the potential benefits of using this image forming apparatus in office settings? - The benefits include improved image quality, extended equipment lifespan, and increased efficiency in document processing.
Original Abstract Submitted
An image forming apparatus includes a moving unit to move a developing roller, a driving portion to be capable of rotating the developing roller in either case where the developing roller is located in a contact position in contact with a photosensitive drum or a separated position separated from the photosensitive drum, an acquiring portion to acquire information on a rotation amount of the developing roller and a notifying portion. The acquiring portion corrects a first information, on the rotation amount of the developing roller in the contact position, to a third information by using a first correction coefficient, and corrects a second information, on the rotation amount of the developing roller in the separated position, to a fourth information by using a second correction coefficient. The notifying portion performs the notification on a lifetime of the developing roller based on the third and the fourth information.
