Abstract
A printing apparatus is provided. The printing apparatus forms a dot in a desired position of a printing sheet by ejecting an ink droplet from a nozzle. A static electricity eliminating mechanism eliminates static electricity generated on the printing sheet by a conductive portion that is arranged in a position to which the ink droplet is ejected from the nozzle or an upstream side of such position on a path through which the printing sheet passes. The conductive portion is formed in at least one of a sheet feed roller and an idle roller that carry the printing sheet. The sheet feed roller or the idle roller is formed by coating a predetermined insulating coating on a surface of a conductive rod-shaped member. The conductive portion is formed by stripping off a part of the coating on the sheet feed roller or the idle roller.
