Title: Recording head for forming images with charged particles

Abstract: A film 33 is adhered using an adhesive layer 32 to the lower surface of an insulation sheet 31 that contacts the peripheral surface of atoner bearing roller. Apertures 34 are formed through the insulation sheet 31, the adhesive layer 32 and the film 33. An indentation portion 37 is formed around each aperture 34 in an upper surface 39 of the insulation sheet 31. Because the insulation sheet 31 and the film 33 are not attached into an integral unit using baking, the resultant member will not warp by differences in thermal expansion of the insulation sheet 31 and the film 33, as would occur if the two were baked together. Because the film 33 is extremely hard and smooth, toner will not pierce into the film 33 .
