Abstract: In the development process of electrophotography, charged dielectric
toner particles move in a micro-gap between the photoreceptor and the
development roller to form images by the action of electrostatic force. To
improve image quality, it is important to clarify the toner particle motion and
the effects of the electric field on this motion. In the present study,
Particle Image Velocimetry (PIV) was applied to measure the toner particle
motion and the results were compared to calculated results. It was confirmed
that the toner velocity increased with increasing electric field intensity, and
that the measurement results agreed with the calculated results. These results
indicated the usefulness of PIV in analyzing toner particle motion in the
development process.
