<p>PROBLEM TO BE SOLVED: To surely prevent filming and the damages to a photoreceptor caused by an external additive with good reproducibility, concerning a toner for electrophotography and an image forming device. SOLUTION: If it is assumed that the mean value of light emission voltage caused by a carbon element originating from a binding resin in a toner particle is VaveA, and the mean value of light emission voltage caused by an inorganic element originating from a particulate in the toner is VaveB, and that A is the weight per unit light emission voltage of the toner particle, B is the weight per unit light emission voltage of the particulate and N is the weight ratio of the particulate to the toner, the coating efficiency of the particulate is controlled, so as to satisfy 0.5<=(B×VaveB)/(N×A×VaveA)<=1.</p> |
