Abstract

PURPOSE:To reduce liquid leakage amount by providing a release agent coating means on an upper roller for fixing, mounting a coating liquid diffusing member from the end of the coating region of the upper roller to its outside and reusing the diffused liquid in the coating part. CONSTITUTION:The fixing part is constituted by an upper roller 11 for fixing, lower roller 12 and release type liquid coating means 13; the upper roller being mounted with a coating liquid diffusing means 16. The upper roller 11 comprises coating Teflon on a hollow aluminum cylinder and is provided with a heating means in its inside. The lower roller is a silicone rubber roller. The coating means 13 consists of a heat-resistant felt 14 and liquid well 15 of release type liquid. The release type liquid transmits to the inside of the heat resistant felt 14 owing to capillarity and is coated on the upper roller 11 only during copying. The diffusing member 16 consists of the heat resistant felt, diffuses the coating liquid and prevents liquid leakage. This considerably reduces the liquid leakage.
