PROBLEM TO BE SOLVED: To provide electrophotographic toner with which the occurrence of a defective image is eliminated and a highly precise image is formed. SOLUTION: When the average value of sticking force working between the electrophotgraphic toner and an electrophotographic photoreceptor measured by a centrifugal separating method is F(nN), and the volume average grain size of the electrophotographic toner is D(μm), and the average value of an electrophotographic toner electrified amount is Q(fC), toner having the F expressed by F=αD+β(Q/D)<2> , wherein α is 0.01-5(nN/μm) and β is 5-230(nN×μm<2> /fC<2> ), is used. |
