摘要： An intermediate transfer medium and the like for image formation includes transferring and fixing a toner image from a photoreceptor onto a recording medium such as paper by using the intermediate transfer medium. The intermediate transfer medium can yield a high gloss desirable for color image and the control of the driving run of the intermediate transfer medium can be maintained readily by reducing the frictional coefficient with the photoreceptor and the intermediate transfer medium can reduce the fog toner transfer rate to prevent the deterioration of the resulting image quality. The surface of the intermediate transfer medium where the image is primarily transferred (primary image transfer medium) is of smooth surface with protrusions dispersed thereon in a manner such that the smooth surface and the protrusions might be discriminated from each other. The relation between the area ratio of the smooth surface on the primary image transfer surface [Cin %] and the height of the protrusions [h (.mu.m)] preferably satisfies the following experimental formula (1):h.ltoreq.19.multidot.(1-Cin/100).sup.-1/2 -24.5 (1)
