IMAGE HEATING APPARATUS AND HEATER FOR USE THEREIN - A simplified explanation of the abstract

This abstract first appeared for US patent application 18514734 titled 'IMAGE HEATING APPARATUS AND HEATER FOR USE THEREIN

Simplified Explanation

The present invention is an image heating apparatus with independently controllable heating blocks to prevent overheating in a no-media passage portion when heating a small-sized image on a recording material.

  • Heater includes multiple independently controllable heating blocks.
  • Each heating block has a first conductor, a second conductor, and a heating element.
  • Electrodes corresponding to heating blocks are located on the second surface of the heater.
  • Electrical contact faces the second surface of the heater to prevent overheating.
  • Suppresses or reduces overheating in a no-media passage portion during heating.

Potential Applications

  • Printing industry for high-quality image printing.
  • Office equipment for efficient document processing.

Problems Solved

  • Overheating in no-media passage portion during small-sized image heating.
  • Ensuring consistent image quality on recording material.

Benefits

  • Improved safety during image heating process.
  • Enhanced efficiency in printing operations.
  • Consistent image quality on various recording materials.


Original Abstract Submitted

The present invention relates to an image heating apparatus that includes a heater including a plurality of independently controllable heating blocks in a longitudinal direction thereof, each including a first conductor, a second conductor, and a heating element. At least one of electrodes corresponding to the respective heating blocks is disposed in an area where the heating element is located in the longitudinal direction on a second surface of the heater that is opposite to a first surface that comes into contact with an endless belt. An electrical contact is arranged so as to face the second surface of the heater. An overheating occurring in a no-media passage portion when an image formed on a recording material having a small size is heated is suppressed or reduced.
