Patent ID: 7389083

Claim:
An image forming apparatus, comprising: an image carrier which holds a developer image; an output medium housing section which contains a medium of an arbitrary size and/or a type for fixing a developer image formed on the image carrier; an output medium guide passage which is defined from the output of a medium housing section to the image carrier, and which guides the output medium; a moving mechanism provided at an arbitrary position of the output medium guide passage to provide a thrust force which moves the output medium from the output medium housing section to the image carrier; a speed detecting mechanism which detects the speed of the output medium moving in the output medium guide passage; and a speed changing mechanism which changes a pressure provided for the output medium from the moving mechanism when the change of the speed of the output medium is detected by the speed detecting mechanism to change the speed by which the output medium is moved when an instruction to perform a regulating mode is given the regulating mode including at least a test copy mode in which a medium is permitted to be conveyed in the output medium guide passage to achieve the change of the speed of the output medium by the speed changing mechanism, and the pressure provided for the output medium is changed based on a result of detection by the speed detecting mechanism.
