Paper Abstract

We studied the optical image density of nonfused toner images on paper as a function of toner mass, focusing on the influence of toner particle size on image density, which we studied both theoretically and experimentally. Four different sizes from the same bulk were used to form the solid image. The toner mass required to obtain sufficient image density decreases with particle size. We defined the normalized number oftoner layers, which determines image density regardless ofparticle size. Using mean toner sizes calculated from a cross section ofparticles, we found that theoretical and experimental results agreed well. These results will be useful in developing high-quality electrophotographic printers.
