IMAGE FORMING APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240094662 titled 'IMAGE FORMING APPARATUS

Simplified Explanation

The patent application describes an image forming apparatus with a unique belt and roller configuration for transferring toner images. Here is a simplified explanation of the patent:

  • Image forming apparatus with specialized belt and roller configuration
  • First belt transfers toner image, first transfer roller in contact with inner surface of first belt
  • Second belt in contact with outer surface of first belt, second transfer roller forms nip portion with first transfer roller through second belt
  • First and second stretching rollers provided upstream and downstream of second transfer roller in rotational direction of second belt
  • First stretching roller has smaller diameter at end portions in rotational axis direction compared to central portion
  • Second stretching roller has larger diameter at end portions in rotational axis direction compared to central portion

Original Abstract Submitted

an image forming apparatus includes an image bearing member, a first belt to which the toner image is transferred, a first transfer roller in contact with an inner surface of the first belt, a second belt contact with an outer surface of the first belt, a second transfer roller to from a nip portion between itself and the first transfer roller through the second belt. first and second stretching roller are provided upstream and downstream of the second transfer roller in a rotational direction of the second belt, respectively. the first stretching roller includes a part, at both end portions in a rotational axis direction, of which a diameter is smaller than that a central portion. the second stretching roller includes a part, at both end portions in the rotational axis direction, of which a diameter is larger than that of a central portion.
