<p>The present invention addresses the problem of providing a positively chargeable toner for nonmagnetic one-component development systems which is free from the image density decrease, paper fogging, and toner flying that are caused by insufficient electrification, and which has excellent conformability to solid printing, while retaining the intact durability. The positively chargeable toner for nonmagnetic one-component development systems at least contains a binder resin, a colorant, and a charge control agent, wherein a styrene/acrylic resin is used as the binder resin and the toner contains fine polytetrafluoroethylene particles and fine inorganic particles, the surface of which has been treated with an aminated treating agent.</p> |
