PURPOSE:To form an electrophotographic full-color image having high sharpness by using a specific toner as a magenta toner and using other specific toners as a cyan toner to form the image. CONSTITUTION:The image is formed by using the toner, of which the volume mean particle size is in a 1-9mu range and the ratio of the magenta coloring agent and binder resin is in a 3:100-15:100 range as the magenta toner and the toner, of which the volume mean particle size is in a 1-9mu range and the ratio of the cyan coloring agent and the binder resin is in a 2:100-15:100 range. The magenta coloring agent to be used includes a quinacridone pigment, rhodamine pigment, azo pigment, etc., as pigments and includes oil soluble dyes such as 'C.I. Solvent Red 49(R)', 'C.I. Solvent Red 52(R)', etc. as dyes. The cyan coloring agent to be used includes a phthalocyanine pigment or oil soluble dyes such as 'C.I. Solvent Blue 40(R)' as dyes. |
