IMAGE FORMING APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18500407 titled 'IMAGE FORMING APPARATUS
Simplified Explanation
The patent application describes an image forming apparatus with various units for charging, developing, transferring, neutralizing charges, and collecting materials on the image bearing member.
- Charging unit charges the image bearing member.
- Developing unit forms a toner image on the latent image.
- Transfer unit transfers the toner image onto a transfer material.
- Charge neutralizer neutralizes the charge of the image bearing member.
- Conductive collecting unit collects material adhering on the image bearing member.
- Developing unit collects residual toner on the image bearing member.
- Voltage application unit sets a potential difference between the collecting unit and the image bearing member.
- Potential Applications:**
- Printing industry - Photocopying machines - Scanners
- Problems Solved:**
- Improves image quality by effectively collecting residual toner. - Prevents image distortion due to charge imbalances. - Reduces material wastage and maintenance costs.
- Benefits:**
- Enhanced image quality - Cost-effective operation - Reduced maintenance requirements
Original Abstract Submitted
An image forming apparatus includes a charging unit that charges an image bearing member, a developing unit that forms a toner image on an latent image formed on the image bearing member, a transfer unit that transfers the toner image onto a transfer material, a charge neutralizer that neutralizes a charge of the image bearing member downstream of a transfer portion and upstream of a charging portion in a rotating direction of the image bearing member, a conductive collecting unit that collects a material adhering on the image bearing member downstream of the transfer portion and upstream of the charging portion, wherein the developing unit collects residual toner on the image bearing member, an voltage application unit sets a potential difference between the voltage applied to the collecting unit and the surface electric potential of the image bearing member not more than a discharge threshold.
