    Abstract: An electrophotographic toner includes toner parent particles containing a binder resin, a colorant and a charge control agent; and an external additive added to the surface of the toner parent particles. The toner further includes positively chargeable silica and polymer beads in addition to large particle diameter silica, small particle diameter silica and titanium oxides. Thus, the toner can maintain its charge quantity and distribution stably even during environmental changes and after long image printing times, thereby preventing the contamination of the non-image part and the filming.

    Abstract: A developing apparatus includes an image receptor and a developing unit having a developing roller facing the image receptor. New toner can be added to the developing unit when existing toner in the developing unit is consumed. The added toner and existing toners are formed of cores and external additives. At least one of the cores or the external additives of the added toner is different from that of the existing toner. When the charge amount of the two toners are Q1 and Q2, respectively, the ratio Q1/Q2 is greater than 0.6 and smaller than 1.7, and the absolute values of Q1 and Q2 are 10 μC/g or greater, respectively.
