PROBLEM TO BE SOLVED: To provide an electrophotographic toner which improves the removability of toner-containing sticking matter sticking on an image bearing member and has superior storage stability such that images of high image quality can be formed. SOLUTION: In the electrophotographic toner, obtained by adding a fluidity imparting agent and a lubricant to a base toner whose average circularity, is 0.94-0.995, a volume average particle diameter of the base toner is set to 3-9μm and melamine cyanurate powder, whose volume average particle diameter is 3-9μm, is added as the lubricant in a ratio of 0.1-2.0 pts.wt. with respect to 100 pts.wt. of the base toner. The ratio of the volume average particle diameter to the number average particle diameter of the base toner is preferably 1.01-1.25. COPYRIGHT: (C)2007,JPO&INPIT
