IMAGE FORMING APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18237998 titled 'IMAGE FORMING APPARATUS

Simplified Explanation

The abstract describes an image forming apparatus that includes a controller to control the position of a roller and a contact and separation mechanism during the image forming process. Here are the key points:

  • The image forming apparatus is used to create and output images on multiple recording materials.
  • The apparatus includes an inner roller and an outer member, which are positioned relative to each other in a circumferential direction.
  • During the period between the passage of a preceding recording material and the arrival of a subsequent recording material at the transfer portion, the relative position between the inner roller and the outer member can be changed.
  • A controller is responsible for controlling a position changing mechanism and a contact and separation mechanism.
  • The position changing mechanism is used to separate the outer roller from a belt, while the contact and separation mechanism is used to change the relative position between the inner roller and the outer member.

Potential applications of this technology:

  • This image forming apparatus can be used in various printing and copying machines to produce high-quality images on multiple recording materials.
  • It can be employed in commercial printing services, office environments, and other industries that require efficient and reliable image reproduction.

Problems solved by this technology:

  • The apparatus allows for precise control of the relative position between the inner roller and the outer member, ensuring accurate image formation on the recording materials.
  • The contact and separation mechanism helps to prevent any unwanted contact or interference between the roller and the belt, which could result in image distortion or damage to the equipment.

Benefits of this technology:

  • The ability to change the relative position between the inner roller and the outer member allows for flexibility in image formation, accommodating different sizes or types of recording materials.
  • The precise control provided by the controller ensures consistent and high-quality image output.
  • The contact and separation mechanism helps to prolong the lifespan of the equipment by preventing unnecessary wear and tear.


Original Abstract Submitted

An image forming apparatus employs a constitution in which, in a case that a relative position between an inner roller and an outer member with respect to a circumferential direction of the inner roller is changed in a period after a preceding recording material passes through a transfer portion and until a recording material subsequent to the preceding recording material reaches the transfer portion during execution of a job for forming and outputting images on a plurality of recording materials, a controller controls a position changing mechanism and a contact and separation mechanism so that a separating operation for separating the outer roller from a belt is performed and then the above described relative position is changed.
