The average diameters of toners C, F and E are about 10μm, which were not large difference with results of
Yashima et al., 9.52 to 10.26 μ m [3]. Toner R is the smallest. Based on the SEM pictures and Table 1, recycle
toners (Toners C, R) were far from spherical and their sizes are much scattered. But new toners (Toners E, F) are
nearly spherical and their diameters were not much scatter. Average diameters measured by the SEM pictures were
slightly smaller than those by the laser diffraction
