Shape coefficients SF-1 and SF-2 of a toner for forming the toner image have values of 100≦SF-1≦125, and 100≦SF-2≦125, respectively. The belt-shaped transfer member has a seamless shape in which a seam is absent. An amount of abrasion of a surface of the belt-shaped transfer member is equal to or less than 10.0 mg. An angle of contact with respect to water of the belt-shaped transfer member is at least 60°. A slide resistance of a surface of the belt-shaped transfer member is equal to or less than 1 N.
