IMAGE FORMING APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18388431 titled 'IMAGE FORMING APPARATUS

Simplified Explanation

The patent application describes an image forming apparatus that adjusts the voltage applied to the transfer member based on environmental conditions and the presence of recording material.

  • The controller sets a limit voltage based on environmental information and detection results when no recording material is present in the transfer portion.
  • The power source is controlled to ensure that the voltage applied to the transfer member during contact with recording material does not exceed the limit voltage.
    • Potential Applications:**
  • Printing technology
  • Photocopiers
  • Scanners
    • Problems Solved:**
  • Ensures consistent image quality under varying environmental conditions
  • Prevents damage to the transfer member and recording material
    • Benefits:**
  • Improved image quality
  • Extended lifespan of equipment
  • Energy efficiency


Original Abstract Submitted

An image forming apparatus includes an image bearing member, a transfer member, a power source, a detecting portion, a controller, an environment detecting portion, and a contact member. In a case that an absolute water content acquired on the basis of environmental information is a predetermined threshold or more, the controller sets a limit voltage on the basis of a detection result of the detecting portion in a state in which the recording material is absent in a transfer portion, and the controller controls the power source so that an absolute value of a voltage applied from the power source to the transfer member during contact of the recording material with the transfer member and the contact member is an absolute value of the limit voltage or less.
