    摘要: A method for fixing full-color toner images on an image receiving member so that the fixed toner images selectively exhibit different glossinesses includes the step of bringing the transferred toner images into contact with a heater, with linear speeds being selectively switched in such a manner that the fixed toner images exhibit a mean surface roughness in a range of 9.5 to 16 &mgr;m at a linear speed (A), and the fixed toner images exhibit a mean surface roughness of less than 8 &mgr;m at a linear speed (B), wherein the linear speed (A) is in a range of 100 to 300 mm/sec, the linear speed (B) is lower than the linear speed (A) by 25 mm/sec or more, and the image fixing temperatures are equal at the linear speeds (A) and (B). A method for fixing full-color toner images with high glossiness on an image receiving member includes the step of bringing the transferred toner images into contact with a belt so that the fixed toner images exhibit a mean surface roughness of less than 8 &mgr;m.
