IMAGE FORMING APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240288792 titled 'IMAGE FORMING APPARATUS
The image forming apparatus described in the patent application includes a photosensitive drum, a charging member, and a developing member.
- The controller initiates a preparation operation by starting the rotation of the photosensitive drum while in contact with the developing member, adjusting charging and developing voltages stepwise to achieve a predetermined potential difference between the surface potential of the photosensitive drum and the developing voltage.
- The controller further controls the changing of the charging voltage to a voltage of the same polarity as during image formation, with an absolute value lower than the discharge start voltage, from a state of no charging voltage application. Subsequently, the charging voltage is adjusted to multiple values of the same polarity as during image formation, with an absolute value equal to or greater than the discharge start voltage.
Potential Applications: - This technology can be applied in various types of image forming devices such as printers, copiers, and scanners. - It can enhance the quality and efficiency of image reproduction in commercial printing and publishing industries.
Problems Solved: - Ensures consistent and accurate charging and developing processes in image forming devices. - Helps maintain the desired potential difference between the photosensitive drum and the developing voltage for optimal image quality.
Benefits: - Improved image quality and clarity in printed materials. - Enhanced reliability and longevity of image forming equipment. - Cost-effective operation due to optimized voltage control.
