IMAGE FORMING APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18226099 titled 'IMAGE FORMING APPARATUS

Simplified Explanation

The abstract describes a patent application related to an image forming mode in which a toner image is formed on a first image bearing member, while no toner image is formed on a second image bearing member. In this mode, a specific voltage is applied to one of the grid electrodes of the second image forming portion, while no voltage is applied to the other grid electrodes.

  • The patent application relates to an image forming mode where a toner image is formed on one image bearing member and not on another.
  • A specific voltage is applied to one of the grid electrodes of the second image forming portion.
  • No voltage is applied to the other grid electrodes of the second image forming portion.
  • The applied voltage is smaller than the minimum value of the voltages applied to the grid electrodes of the first image forming portion.
  • The applied voltage is larger than the absolute value of the target potential of the surface of the second image bearing member.

Potential applications of this technology:

  • This technology can be used in printers, copiers, and other image forming devices.
  • It can be applied in situations where selective toner image formation is required.

Problems solved by this technology:

  • This technology allows for the formation of toner images on specific image bearing members while preventing toner image formation on others.
  • It provides a method to control the toner image formation process in a precise and selective manner.

Benefits of this technology:

  • Improved image quality and accuracy by selectively forming toner images.
  • Enhanced control over the image forming process.
  • Reduction in toner wastage and cost savings.



Original Abstract Submitted

In an image forming mode in which, a first image forming portion forms a toner image on the first image bearing member and a second image forming portion does not form a toner image on the second image bearing member, thereby forming an image on a recording material, a first voltage smaller than a minimum value of absolute values of a plurality of voltages applied to a plurality of grid electrodes of the first image forming portion and larger than an absolute value of a target potential of a surface of the second image bearing member in the image forming mode is applied to one of the plurality of grid electrodes of the second image forming portion, and no voltage is applied to the other grid electrodes except the grid electrode to which the first voltage is applied among the plurality of grid electrodes of the second image forming portion.
