<p>PURPOSE:To obtain a toner excellent in color mixture property when fixing, free from the welding of wax to a triboelectrified member even when continuously printing and excellent in offsetting resistance and printing stability by consisting of a binding resin, an organic pigment and the wax dispersed CONSTITUTION:The subject is used for a non-magnetic one component development and consists of the binding resin, the organic pigment and the wax subjected to high sheared predispersion treatment. An epoxy resin, a polyester resin or the like is used as the toner binding resin and when particularly the polyester resin is used, excellent color mixture property and transparency are attained. As a used benzine base organic pigment, e.g. C.I. 21090 of color index or the like, as a quinacridone base organic pigment, C.I. 73916 of color index is used, as a rhodamine base organic pigment, C.I. 45160 of color index is used. These pigments has excellent dispersibility in the binding resin and has excellent spectral reflectance characteristic.</p> |
