<p>PROBLEM TO BE SOLVED: To provide electrophotographic toners for a one-component developer which prevent a developing sleeve and layer thickness regulating member (blade and roller) against the contamination by fusion even in long-term use and prevent photoreceptor filming. SOLUTION: Polyester resins which do not contain THF insoluble components, are <=4 wt.% in the content ratio of the components below a molecular weight 500 in the molecular weight distribution in gel permeation chromatography and have one peak in a region of a molecular weight 3,000 to 9,000 are used as the binder resins of the electrophotographic toners for the one-component developer.</p> |
