Abstract
A process for forming a full-color image, wherein the 4 color toners each have an apparent viscosity at 105° C. of 50,000 to 300,000 Pa·s and an apparent viscosity at 130° C. of 3,000 to 30,000 Pa·s, and as a color toner arranged at the outermost layer on a transfer medium among the 4 color toners, a toner, in which a maximum peak or a shoulder peak is present between 105° C. and 130° C. in a temperature-logarithmic melt viscosity graph, is used, and as the other color toners arranged at lower layers than the outermost layer, toners, in which neither the maximum peak nor the shoulder peak is present between 105° C. and 130° C., are used.
