Abstract
Abstract Disclosed is an image-receiving sheet having better toner-fixing ability, an excellent image quality and high carriage quality in electrophotographic copying machines and printers. In an image-receiving sheet in which a layer containing a binder and a filler is formed on one surface of a substrate 1 , the Beck smoothness of the containment layer is 2000 seconds or less and the haze of the image-receiving sheet is 5 to 15% to stabilize the carriage quality and to obtain a high quality image from OHP projectors. The containment layer is either one of a receptor layer 2 for recording an image or a backface layer 3 and in the image-receiving sheet, a layer having a Beck smoothness of 20000 seconds or less is formed on the surface opposite to the surface of the substrate 1 on which the containment layer is formed, thereby further bettering the carriage quality. Moreover, resistance control layers 41, 42 are formed on an image-receiving surface and/or the outermost layer of the backface, or between the receptor layer 2 and the substrate 1 or between the backface 3 and the substrate 1 , thereby maintaining better antistatic ability and toner-fixing ability.
