To easily and stably obtain a high-definition and high-quality color image without color slurring and to reproduce the excellent color image without selecting final material to be transferred.

After forming a toner image 3 of one or more colors on an electrophotographic photoreceptor 11 having a peelable surface by using liquid developer in an electrophotographic process, the toner image 3 on the photoreceptor 11 is contact-transferred on a primary receptor 20, and transferred on the material to be trasferred 30 provided with a tight contact layer (M) 5 principally containing thermoplastic resin (AM) whose glass transition point is ≤80°C or whose softening point is ≤90°C so as to form the color image (route (a)). Furthermore, it is conceivable to transfer the toner image through transfer layers (T) 7, 7' and 8 (routes (b) to (d)).
