Dependence of electrostatic field on properties of paper in a two-dimensional toner image transfer nip
AbstractElectrostatic fields in the toner image transfer nip of laser printers were calculated by exact solution of the Poisson equations for a two-dimensional (2D) model and by applying for the paper the approximation of dielectric thickness. Both the distribution and location of the electric field strength component parallel to the paper surface were investigated and field values were calculated for different paper and toner parameters. The conditions of the occurrence of Paschen discharge in the toner image transfer nip were analysed.
