In development process of electrophotography, charged toner particles move to form image by the electrostatic force in a micro-gap between photoreceptor drum and development roller. To improve image quality and prevent image defects, it is important to clarify the motion of toner particles and to study the effects of electric field. In the present study, PIV system is used to measure the velocity of toner particles and the measured results were discussed comparing with the calculated electric field. It was confirmed that the velocity of toner particles increased with increasing electric field intensity. These results show the usefulness of PIV system to measure the motion of toner particles in development process.
