TWO-COMPONENT DEVELOPER AND METHOD FOR FORMING IMAGE BY USING THE SAME |
| 摘要 |
PROBLEM TO BE SOLVED: To provide a two-component developer with which a high-quality image can be formed and to provide an electrophotographic method for forming an image by using the developer. SOLUTION: The two-component developer consists of a carrier and a toner in which wax is dispersed. The toner is prepared by using titanium oxide fine powder and silica fine powder together in the ranges of the weight WTi of titanium oxide and the weight WSi of silica satisfying the conditions of (1) 0.4<WTi/WSi<1.0 and (2) 1.0<WTi+WSi<2.0. The two-component developer can be effectively used for the formation of an image in an electrophotographic image forming device having a toner recycling mechanism and a rotating speed of a photoreceptor having a specified structure as fast as 350 to 550 mm/sec. |
