US 2003/0210293 A1 · Image forming apparatus

Abstract

It is an object of the present invention to provide an image forming apparatus capable of improving the quality of an image recorded on a recording medium and simplifying the structure. A release mechanism forces a carriage possible state of an upstream carrying mechanism to be released in at least a stop state before recording paper is separated downstream from an upstream carrying mechanism, and thereafter, printing is performed on the recording paper, thus minimizing the difference between the contact pressure of the upstream carrying mechanism to the recording paper and that of the downstream carrying mechanism, and variations in carrying speed due to the changes of the carrying position of the recording paper to prevent variations in the volume of carriage of the recording paper.

Dependent claims

An image forming apparatus comprising:

recording means for recording a desired image on a recording medium;
recording-medium carrying means capable of carrying the recording means, the recording-medium carrying means including upstream carrying means arranged along a carrying path and upstream of the recording means and downstream carrying means arranged along the carrying path and downstream of the recording means;
release means capable of releasing a carriage-possible state of the recording medium in the upstream carrying means;
and
control means for forcibly releasing the carriage-possible state to control a carrying force to be applied to the recording medium before the recording medium is separated downstream from the upstream carrying means, based on predetermined recording-medium carrying position information.
