    摘要： An image forming method includes: disposing a white toner image of a white toner and a colored toner image of a colored toner in the order named; and heat-fixing these toner images to a recording medium. The white toner and the colored toner satisfy the following relational expressions (1) and (2). In the expressions, G′0(w), G′10(w) and G′20(w) respectively represent storage moduli of the white toner 0 seconds after, 10 seconds after and 20 seconds after start of time variance measurement, and G′0(c), G′10(c) and G′20(c) respectively represent storage moduli of the colored toner 0 seconds after, 10 seconds after and 20 seconds after the start of time variance measurement. The storage moduli are obtained by the time variance measurement at 90° C. (G′10(c)/G′0(c))
