Abstract:
1. A belt feed apparatus, comprising: an endless belt member that is carried on a plurality of carry members and capable of circulatory motion thereon; a belt back surface member that is disposed on a back surface side of the endless belt member, the belt back surface member including a close portion disposed close to the endless belt member to such a degree that, when the endless belt member stands stationary, the close portion is prevented from touching the endless belt member, and while the endless belt member is circulating, the close portion can be contacted with the endless belt member irregularly; and a non-sticking portion that includes a non-sucking surface contactable with the endless belt member to prevent the endless belt member from being electrostatically sucked to the close portion, the non-sucking surface being provided in an entire portion or part of a surface of the close portion opposed to the endless belt member, and due to the existence of the non-sucking surface, the non-sticking portion being able to prevent the endless belt member from sticking to the close portion, wherein the endless belt member is made of a polyamide-imide system resin, and the non-sucking surface is formed by providing a polyurethane system resin sheet member onto the belt back surface member.
