IMAGE FORMING APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240337980 titled 'IMAGE FORMING APPARATUS
Simplified Explanation:
The patent application describes an image forming apparatus with a mechanism that controls the contact and separation of a developing roller from a photosensitive member. The apparatus includes a motor to drive the photosensitive member and a control portion to detect failures in the contact/separation mechanism.
- The apparatus includes a photosensitive member, a developing roller, and a contact/separation mechanism.
- A motor drives the photosensitive member, while the control portion monitors the mechanism for failures.
- The mechanism can switch between a contact state and a separation state to ensure proper image formation.
Key Features and Innovation:
- Mechanism to control contact and separation of developing roller and photosensitive member.
- Motor to drive the photosensitive member.
- Control portion to detect failures in the contact/separation mechanism.
Potential Applications:
The technology can be used in various image forming devices such as printers, copiers, and scanners.
Problems Solved:
The technology ensures proper contact between the developing roller and photosensitive member, leading to high-quality image formation.
Benefits:
- Improved image quality.
- Enhanced reliability of image forming apparatus.
- Efficient operation of the contact/separation mechanism.
Commercial Applications:
Potential commercial applications include office printers, commercial printing presses, and photocopiers.
Questions about Image Forming Apparatus:
1. How does the contact/separation mechanism contribute to the overall performance of the image forming apparatus? 2. What are the key components that make up the image forming apparatus and how do they work together?

Original Abstract Submitted
an image forming apparatus includes: a photosensitive member; a developing roller; a contact/separation mechanism configured to switch between a contact state in which the developing roller is brought into contact with the photosensitive member and a separation state in which the developing roller is separated from the photosensitive member; a photosensitive-member motor configured to rotate and drive the photosensitive member; and a control portion. the control portion configured to determine that the contact/separation mechanism is in a failure state in a case where a torque of the photosensitive-member motor is not detected to have changed by at least a predetermined value within a predetermined time after a predetermined reference timing.
