IMAGE FORMING APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18472828 titled 'IMAGE FORMING APPARATUS
Simplified Explanation
The image forming apparatus described in the patent application includes a drum unit, a developing unit, a developing roller bearing, a guide portion, and an urging portion. The drum unit contains a photosensitive drum, while the developing unit houses a developing roller. The developing roller bearing supports the developing roller and can move radially and rotate axially with respect to the developing unit. The guide portion, formed in the drum unit, directs the developing roller bearing towards and away from the photosensitive drum. The urging portion pushes the developing unit in a direction that causes the developing roller to press against the photosensitive drum. Additionally, the developing unit features a restriction portion that limits the rotation of the developing roller bearing within a predetermined range.
- Drum unit with photosensitive drum
- Developing unit with developing roller
- Developing roller bearing supporting and moving radially/rotating axially
- Guide portion in drum unit directing developing roller bearing
- Urging portion pushing developing unit towards photosensitive drum
- Restriction portion in developing unit limiting rotation of developing roller bearing

Original Abstract Submitted
An image forming apparatus includes a drum unit, a developing unit, a developing roller bearing, a guide portion, and an urging portion. The drum unit includes a photosensitive drum. The developing unit includes a developing roller. The developing roller bearing supports the developing roller and can move radially and rotate axially with respect to the developing unit. The guide portion is formed in the drum unit and guides the developing roller bearing in directions toward and away from the photosensitive drum. The urging portion urges the developing unit in such a direction that it presses the developing roller against the photosensitive drum. The developing unit includes a restriction portion that restricts the rotation of the developing roller bearing with respect to the developing unit within a predetermined range.
