A developing unit and a stirring unit are provided, and in order to suppress toner scattering that may occur after a development operation has been halted for a long time, and thereby suppress contamination of the apparatus interior, the developer in a developing machine is transferred to a stirrer serving as a developer storage unit on the exterior of the developing machine when the development operation ends. Further, to extend the life of the developer, a range in which an angle of a restricting member upstream side central angle α, which is a central angle of the surface of a developing roller serving as a developer carrier on the upstream side of a restricting member opposing position opposing a doctor blade serving as a developer amount restricting member in a surface motion direction of the developing roller, is not less than 0[°] and not more than 60[°] is set as a low magnetic flux density area γ in which the maximum value of a normal direction magnetic flux density on the surface of the developing roller is not more than 30 [mT].
