PROBLEM TO BE SOLVED: To obtain a nonmagnetic one-component developer which has high fluidity without adding a large amount of silica or using a spherical toner, prevents the sticking of a toner on a layer thickness regulating member and a developer conveying member and makes the thickness of a toner layer uniform. SOLUTION: Silica having 25-80 nm average particle diameter as an additive is added to a nonmagnetic toner by 0.2-1.0 wt.% of the total weight of the nonmagnetic toner to obtain the objective nonmagnetic one-component developer. |
