In the improved image forming method, an electrophotographic photoreceptor drum carrying an a-Si (amorphous silicon) photoconductor having a SiC (silicon carbide) is subjected to imagewise exposure to form a latent electrostatic image on the photoconductor, the latent image is then developed with a toner the particles of which are coated with a polymer having a cohesive energy constant G of at least 280, and the toner image formed on the photoconductor is adhesive-transferred onto an intermediate transfer element having an adhesive layer formed from an adhesive that is based on a urethane (meth)acrylic resin and which further contains at least one member selected from among an acrylic rubber, a saturated polyester resin and a fluorine-containing additive, with the toner image on the adhesive layer being retransferred onto a support to form a final image. To form a color image, this process including the retransfer step is repeated either three or four times depending on the number of colors to be reproduced. The toner image formed on the final support is such that is has been completely transferred form the photoconductor and hence has high contrast and quality in the absence of density unevenness and other defects.
