摘要： PROBLEM TO BE SOLVED: To provide an image forming method adopting a two-component developing method capable of obtaining a stable image without the occurrence of an abnormal image (fixation offset image) even in the case of loading the image forming system to a machine having a lot of thermal stress and mechanical stress on developer, and to provide two-component developing toner used for the image forming method. SOLUTION: As for the image forming method using the two-component developer with wax dispersed and constituted of the toner and carrier, and utilizing an air flow as a recovered toner carrying means in a recycling system for returning the recovered toner which is recovered by a cleaning in the electrophotographic image forming device employing oil-less fixation to a developing part, the toner having a looseness apparent density of >=0.3 g/cc is used for the image forming method.
