Abstract
Spherical polymer particles have at least two peaks, or have at least one peak and a shoulder formed on the high-molecular weight side with respect to the peak, in their chromatogram obtained by gel permeation chromatography. The spherical polymer particles can turn into a viscoelastic form in a broad temperature range, and promise a superior heat fixing performance of toner images especially when used as image forming toner.
