Abstract
PURPOSE: To obtain a magnetic toner showing high fixability under low pressure, superior fluidity and superior image quality by controlling the particle size distribution of a magnetic toner.
CONSTITUTION: A magnetic toner is prepared so that particles showing a ≤15μm particle size distribution and having a peak at 5W12μm are ≤50wt% and particles showing a 15W50μm particle size distribution and having a peak at 25W44μm are ≥50wt%. This magnetic toner having ≤50μm particle size and two peaks in the particle size distribution is highly fluidizable, so it is smoothly supplied to a magnetic roll. The resulting image is homogeneous and has high resolution. In addition, this toner shows sufficient fixability under low pressure. Thus, by controlling the particle size distribution, a magnetic toner showing high fixability under low pressure, superior fluidity and superior image quality can be obtd.
