An object of the present invention is to provide a non-magnetic toner for development in which high-quality image characteristics can be stably obtained from an initial stage to a life end. The toner comprises at least 80% or more of a polyester resin having a glass transition point of 50 ° C. to 65 ° C. in a toner comprising at least a binder resin, a wax and a colorant. Alternatively, a compound selected from polyethylene, which has a melting point of 50 ° C. to 90 ° C., and the toner powder having undergone the pulverizing step is heated with a hot air having a temperature higher than the glass transition point of the binder resin and the melting point of the wax. And the arithmetic average value of the circularity of the processed toner powder is 0.73 or more and 0.84 or less, and a fatty acid metal salt having a volume average particle size of 4 μm or less is added to the processed toner powder. Is a non-magnetic toner for development. [Selection diagram] None |
