ABSTRACT:
Provided is an image forming method, in which image glossiness is the same as a recording medium regardless of the values of an image density or an image area percentage, especially an image excellent in not only color reproducibility but granularity is obtained and in addition, no cracks are produced in the surface layer of the recording medium after the image is formed, and a recording medium preferably used in the method.
The method comprises the steps of: forming a toner image on an image carrier; placing the image formed on the image carrier on a transparent thermoplastic resin layer of a recording medium in a close contact condition, wherein the transparent thermoplastic resin layer is provided at a surface roughness (Ra) of 1.0 .mu.m or less on an opaque base of the recording medium; and heating the toner image thus placed in the close contact condition to transfer and fix the image on the transparent resin layer. The image carrier is heated to a surface temperature thereof higher than a softening point (Tmt) of a toner before the image carrier reaches a toner image transfer position and the recording medium is preferably separated from the toner image carrier when a temperature of the transparent resin of the surface of the recording medium is lower than the softening point (Tmp) by more than 10.degree. C. at a position downstream of the toner image transfer position.
