<p>PROBLEM TO BE SOLVED: To provide electrophotographic dry process toners which are free of the degradation in image density and do not produce black dots on a photoreceptor when continuous copying of multiple sheets is performed. SOLUTION: The electrophotographic dry process toners are formed by adhering a multi component oxide (TiO2 -SiO2 ) of titanium oxide and silica to the toner particles of the electrophotographic toners essentially consisting of the toner particles containing at least a binder resin and coloring agents.</p> |
