Abstract
A numerical study was carried out on the electrostatic sticking of a charged paper to photoreceptor in electrostatic transfer process for electrophotography. Numerical procedures to predict sticking of the paper were presented which consists of (1) determination of initial angle of the paper,(2) estimation of electric field intensity, (3) estimation of charge on paper created by Paschen's air breakdown, (4) estimation of electrostatic force acting on the paper and (5) calculation of deformation of paper. Deformation of the charged paper in electric field was numerically simulated according to the procedures and the dependencies of paper sticking on photoreceptor size and initial angle of paper were quantitatively clarified. It is clarified that the smaller and softer photoreceptor improves sticking of paper.
