Abstract

PURPOSE:To prevent offset, by installing a member which fixes toner images on the supporting body and by giving a mold releasing property to the working surface of the member by applying either SnO2, SnO2-TiO2 series mixed crystal body or SnO2-BaSO4 series mixed crystal body. CONSTITUTION:A roller 1 at the side which contacts with a toner image T on a copying material C is composed of a pipe-shaped rigid body, such as metallic pipe, etc., having a good heat conductivity and a heat source 3 is installed in the roller 1. Another roller 2 (pressure-contacting roller) which is paired with the roller 1 (fixing roller) is made of an elastic body, such as rubber, etc., and a layer 7 of an elastic body, such as silicone rubber, etc., is installed on the outer periphery of the roller 2. In this invention, this layer is constituted by charging either SnO2, SnO2-TiO2 series mixed crystal body or SnO2-BaSO4 series mixed crystal body, and a mold releasing property is given to the layer. While the fixing operation is tested under three different conditions, low temperature-low humidity, normal temperature-normal humidity, and high temperature-high humidity, no offset is generated in any case.
