PROBLEM TO BE SOLVED: To form a full-color toner image using toners for developing electrostatic images of four colors of yellow, magenta, cyan and black without causing the paper to be wound around a fixing drum when high-speed fixing is performed. To provide an oilless image forming method in which dirt is not generated even if an oil application mechanism is not provided on a fixing heating member. In an image forming method for forming a full-color toner image by superimposing toners for developing electrostatic images of four colors of yellow, magenta, cyan and black on a transfer material, the release agent content of black toner is 15 The release agent content of the other color toners is 8% by mass or more and 23% by mass or less, and the release agent content of the black toner is that of the other color toners. An image forming method characterized by being 4 to 15% larger than the content of the agent. [Selection figure] None |
