PROBLEM TO BE SOLVED: To obtain a stable transfer characteristic regardless of the use history of toner. SOLUTION: In the image forming device of a cleaner-less system using the toner obtained by covering a resin base particle surface with an external additive, sticking force between a first transfer body (19) and the toner is made larger than sticking force between image carriers (10M, 10C, 10Y and 10Bk) and the toner, and also sticking force between the first transfer body and resin base particles is made larger than sticking force between the image carriers and the resin base particles. |
