PROBLEM TO BE SOLVED: To provide an image forming device capable of stably obtaining a high-quality toner image over a long term, and obtaining a high-quality fixed image having no image defect over a long term even in the image forming device of a developing and cleaning simultaneously executing system especially. SOLUTION: In this image forming device; an electrostatic latent image formed on the electrified surface of the surface of an image carrier 21 uniformly electrified by an electrifying member 22 is developed with toner so as to form a toner image, and the toner has at least resin base particles and one or more kinds of additive for reforming the property of the resin base particles, and is constituted so that relation A/B>1 may hold between A and B when it is assumed that the absolute value of the triboelectrification amount of the resin base particles to the additive is A (mC/kg) and the absolute value of the triboelectrification amount of the member 22 to the additive is B (mC/kg). |
