A multi-color image-forming process is provided, which comprises a step of transferring an image to an image-receiving sheet by irradiating a heat transfer sheet with laser light in a recording device provided with a recording drum to form the image on the image-receiving sheet, wherein (a) the heat trasfer sheet comprises a image forming layer having Rz of the surface of 0.5 to 2.5 mum, the image-receiving sheet comprises a image-receiving layer having Rz of the surface of 0.5 to 1.5 mum, the image-receiving sheet has a longitudinal thermal shrinkage of 1.0% or less, the image-receiving sheet has a crosswise thermal shrinkage of 1.0% or less, and the a multi-color image-forming process comprises a step of retransferring the image which has been transferred to the image-receiving sheet to a final image carrier, the retransferring is effected using a pair of heated rolls each having a diameter ranging from 50 mm to 350 mm wherein the temperature of the various rolls are set to from 80° C. to 250° C.; (b) wherein the multi-color image-forming process comprises a step of cleaning a surface of the heat transfer sheet and a surface of the image-receiving sheet by bringing the heat transfer sheet and the image-receiving sheet into contact with a pressure-sensitive adhesive roller having a pressure-sensitive adhesive material on a surface of the roll, the pressure-sensitive adhesive roller being provided either at a section where the heat transfer sheet is fed or transported, or at a section where the image-receiving sheet is fed or transported, the pressure-sensitive adhesive roller has a pressure-sensitive adhesive material having a hardness (JIS-A) of 15 to 90, the heat transfer sheet comprises a image-forming layer having a Smoothster value of 1.0 to 20 mmHg (0.13 to 2.7 kPa), and the image-receiving layer has a surface having a Smoothster value of 0.5 to 30 mmHg (0.07 to 4.0 kPa); or (c) both the longitudinal stiffness (Msr) and the crosswise stiffness (Tsr) of the image-receiving sheet are from 40 to 90 g, Msr/Tsr is from 0.75 to 1.20, the surface roughness of the aforesaid recording drum and image-receiving layer each are from 0.01 to 12 mum as calculated in terms of Rz, and the diameter of the aforesaid recording drum is 250 mm or more.
