ELECTROPHOTOGRAPHIC TONER

摘要

PURPOSE: To obtain an electrophotographic toner having superior transferability and satisfactory ability of cleaning. CONSTITUTION: This electrophotographic toner is a mixture of an amoprhous toner with a spherical toner, the volume average particle diameter of the amorphous toner is larger than that of the spherical toner and the spherical toner is mixed by <=5wt.%. When the area of a circule having the absolute max. length of the toner particles of the spherical toner as the diameter is represented by Sc and the average practical projection area of the toner particles is represented by Sr, the value of Sc/Sr is in the range of 1.0-1.5.
