Abstract:
1. A method for forming an image with a set of electrostatic charge image developing toners using a digital electrophotographic method, provided that the set of electrostatic charge image developing toners comprises a black toner and a light gray toner, and the black toner and the light gray toner each comprise toner particles containing a binder resin, a colorant and a releasing agent, the method comprising the steps of: forming an electrostatic latent image on an image support; developing the electrostatic latent image with the black toner to form a black toner image; developing the electrostatic latent image with the light gray toner to form a light gray toner image; and fixing the black toner image and the light gray toner image, wherein the black toner contains a wax having an endothermic peak in the range of 60 to 105° C.; and the light gray toner has a transmittance in the range of 40 to 90%, provided that the transmittance is measured for a fixed light gray toner image formed on a polyethyleneterephthalate sheet with an adhered amount of the light gray toner of 4.0 g/m 2 , and the light gray toner contains a wax having an endothermic peak in the range of 60 to 105° C.
