Claims

[Scope of utility model registration request]

When a load of more than a predetermined value is applied to the trailing edge of the recording paper in the conveyance direction of multiple pairs of conveyance rollers arranged in the paper conveyance path of an electrophotographic device, etc., the value of the conveyance force for the recording paper is automatically changed. Using a pair of conveyor rollers configured to be adjusted to a small value,
The paper is characterized in that the rotational speed of the pair of conveyance rollers is set higher than the rotational speed of the pair of conveyance rollers disposed behind the pair of conveyance rollers in the direction of travel, so that the conveyance speed of the recording paper can be increased as the recording paper advances. Conveyance device.
