摘要

PROBLEM TO BE SOLVED: To provide electrostatic image developing toner the cracks and deformation of which are suppressed, and in which the reduction of fluidization and carrier contamination are suppressed.;SOLUTION: The electrostatic image developing toner is characterized in that the volume average particle diameter (D50v)is 5 to 7 μm, the volume average particle size distribution (GSDv) is ≥1.31 and 1.41, and the particle content of the toner with a piece particle diameter of ≤2.52 μm is 5 piece%.;COPYRIGHT: (C)2010,JPO&INPIT
