IMAGE FORMING APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18054105 titled 'IMAGE FORMING APPARATUS

Simplified Explanation

The abstract describes an image forming apparatus that includes a heating rotary member and a pressing rotary member. These members form a fixing nip portion where heat and pressure are applied to fix a toner image onto a recording medium. The apparatus also includes a winding roller to collect unfixed toner, a motor to rotate the winding roller, a contact member to touch the web wound around the roller, a variable resistor to change resistance based on the contact member's position, and a control unit to regulate the motor's rotation.

  • The image forming apparatus includes a heating rotary member and a pressing rotary member.
  • The heating and pressing rotary members form a fixing nip portion.
  • Heat and pressure are applied at the fixing nip portion to fix a toner image onto a recording medium.
  • The apparatus includes a winding roller to collect unfixed toner.
  • A motor is used to rotate the winding roller.
  • A contact member touches the web wound around the winding roller.
  • A variable resistor changes resistance based on the position of the contact member.
  • A control unit regulates the amount of rotation of the motor.

Potential Applications

  • This image forming apparatus can be used in various printing devices such as laser printers, photocopiers, and multifunction printers.
  • It can be utilized in commercial printing services, offices, and homes where high-quality prints are required.

Problems Solved

  • The apparatus solves the problem of fixing toner images onto recording media by providing a fixing nip portion where heat and pressure are applied.
  • It addresses the issue of collecting unfixed toner by incorporating a winding roller to wind up the web.
  • The variable resistor allows for precise control of the motor's rotation, ensuring efficient winding and collection of the toner.

Benefits

  • The image forming apparatus provides a reliable and efficient method for fixing toner images onto recording media.
  • It ensures high-quality prints with excellent toner adhesion.
  • The winding roller and variable resistor enable effective collection of unfixed toner, reducing waste and maintenance requirements.


Original Abstract Submitted

An image forming apparatus includes a heating rotary member and a pressing rotary member. The pressing rotary member and the heating rotary member form a fixing nip portion and are configured to apply heat and pressure to a toner image carried on a recording medium at the fixing nip portion, thereby fix the toner image onto the recording medium. The image forming apparatus further includes a winding roller configured to wind up a web used to collect toner that is not fixed to the recording medium, a motor configured to rotate the winding roller, a contact member configured to contact an outside surface of the web wound around the winding roller, a variable resistor disposed so as to be able to change a resistance in accordance with a position of the contact member, and a control unit configured to control an amount of rotation of the motor.
