Abstract
A film,is adhered using an adhesive layer,to the lower surface of an insulation sheet,that contacts the peripheral surface of atoner bearing roller. Apertures,are formed through the insulation sheet,, the adhesive layer,and the film,. An indentation portion,is formed around each aperture,in an upper surface,of the insulation sheet,. Because the insulation sheet,and the film,are not attached into an integral unit using baking, the resultant member will not warp by differences in thermal expansion of the insulation sheet,and the film,, as would occur if the two were baked together. Because the film,is extremely hard and smooth, toner will not pierce into the film
