ABSTRACT:
An image forming apparatus including an image forming unit which forms an image on a recording sheet, a casing which houses the image forming unit and holds the image forming unit, a conveying roller which contacts the recording sheet to be conveyed in the casing, conveys the recording sheet, and is supported to rotate by the casing, a cover which opens and closes an opening formed in a portion of the casing which corresponds to the conveying roller, and a pushing unit. If the cover is closed, the pushing unit exerts a pushing force to push the conveying roller toward the recording sheet to act on a spindle of the conveying roller. If the cover is opened, the pushing unit releases the pushing force by moving in association with the cover.
