ABSTRACT:
An improved belt-type fixing unit in which an unfixed developer on a sheet is not disordered by a disturbed air flow when the sheet enters a contact section of a fixing belt and a pressure roller which comes in pressure contact with it, i.e., a fixing section. In the belt-type fixing unit, a space just before the entry of the sheet into the fixing section is obtusely formed so as to secure a sufficient space for the disturbed air flow to escape.
