IMAGE FORMING APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18052465 titled 'IMAGE FORMING APPARATUS
Simplified Explanation
The abstract describes an image forming apparatus that includes various components such as a photosensitive member, a developing roller, motors, and switching units. The apparatus is designed to transmit driving force to the developing roller, switch between driving force transmission and non-transmission states, and switch between contact and separated states of the developing roller and photosensitive member.
- The image forming apparatus includes a photosensitive member, a developing roller, motors, and switching units.
- The drive-train transmits the driving force from the first motor to the developing roller.
- The second motor drives the drive switching unit and the development switching unit.
- The drive switching unit can switch between a state where the driving force is transmitted and a state where it is not transmitted.
- The development switching unit can switch between a state where the developing roller and photosensitive member are in contact and a state where they are separated.
- The development switching unit operates in conjunction with the drive switching unit.
- When the drive switching unit transitions from non-transmission to transmission state and the current flowing through the first motor changes, the second motor is stopped before the developing roller contacts the photosensitive member while still driving the first motor.
Potential applications of this technology:
- Image forming devices such as printers, copiers, and scanners could benefit from this image forming apparatus.
- Any application that requires precise control of the contact between a developing roller and a photosensitive member could utilize this technology.
Problems solved by this technology:
- This technology solves the problem of ensuring proper contact between the developing roller and the photosensitive member in an image forming apparatus.
- It also addresses the issue of controlling the driving force transmission and non-transmission states accurately.
Benefits of this technology:
- The image forming apparatus provides improved control and accuracy in the contact between the developing roller and the photosensitive member.
- The ability to switch between driving force transmission and non-transmission states allows for efficient operation and reduced wear on components.
- The technology offers enhanced reliability and performance in image forming devices.
Original Abstract Submitted
An image forming apparatus includes a photosensitive member, a developing roller, first and second motors, a drive-train having a drive switching unit, and a development switching unit. The drive-train transmits a driving force of the first motor to the developing roller. The second motor drives the drive switching unit and the development switching. The drive switching unit switches between a driving force transmission state and a driving force non-transmission state. The development switching unit switches between a developing roller-photosensitive member contact state and a developing roller-photosensitive member separated state, and operates with an operation of the drive switching unit. When the drive switching unit transitions from the non-transmission to the transmission state and a detected magnitude of a current flowing through the first motor has changed, the second motor is stopped before the developing roller is brought into contact with the photosensitive member while driving the first motor.
