PURPOSE:To enable the formation of a plurality of copies with one latent image by using a plastic film having many pores as the intermediate medium of a transferring and heat fixing apparatus and applying an adhesive such as silicone oil to the film. CONSTITUTION:A plastic film sheet 10 has pores 10a having 0.01-50mum diameter, and the porosity is 1-98%. The sheet 10 is coated with an adhesive 11 such as silicone oil in the form of a layer having <=10mum thickness at a coating section 29, 30. The preferred adhesive is methylsilicone, phenylsilicone, fluorosilicone, fatty acid modified silicone oil, nitrilesilicone oil or chlorosilicone oil. A toner image formed on an electrostatic belt 18 is transferred onto the coated plastic film 10 as an intermediate medium without using charges, and then it is transferred onto transfer paper 27 and fixed with heating.
