PROBLEM TO BE SOLVED: To achieve small size and low cost while stabilizing quality by cutting down number of parts and by making functions intensive. SOLUTION: In this image forming device, a developer carrier 15 with a magnetic field generating means provided inside and carrying and transporting 2 component developers containing toner and magnetic carrier 22a, a 1st restricting member 17 to restrict the quantity of the developer that is carried and transported on the developer carrier 15, a developer containing part 16 containing the developer scraped off by the 1st restricting member 17 and a toner containing part that is adjacent to the developer containing part 16 and feeding the toner to the developer carrier 15 are provided. Then, the toner is substance containing at least binding resin, magnetic substance and wax, contained quantity of FeO in the magnetic substance is 16 to 25 wt.%, the magnetic substance is spherical magnetic powder with an average particle diameter for volume of 0.2 to 0.3 μm and contained quantity of the magnetic substance in toner resin is 10 to 40 wt.%. |
