Abstract
Toner scatter is one of the major image degradations at 2nd transfer unit in xerographic process. To clarify the mechanism of the phenomenon, one-dimensional numerical simulations on the electric field including effects of discharge were executed to investigate electric forces on toner particles. In the simulation, the electric field intensity in the process direction on a printed area was defined as a characteristic value for evaluating the degree of toner scatter. As a result, it was found that the electric field which raises the toner scatter was generated when the charge on media in a contact area is not sufficient. Factorial effects calculated by the simulation model were in good agreement with the experimental ones.
