ELECTROSTATIC CONVEYANCE METHOD FOR ELECTROSTATICALLY CHARGED TONER AND ELECTROSTATIC CONVEYANCE DEVICE FOR ELECTROSTATICALLY CHARGED TONER

摘要

PROBLEM TO BE SOLVED: To solve the problem that the stagnation of toners is resulted when even a piece of electrodes for electrostatic conveyance is disconnected. ;SOLUTION: The electrostatic conveyance method for the electrostatically charged toner of conveying the electrostatically charged image forming toners by an insulating substrate formed with electrode trains for electrostatic conveyance comprises disposing a common electrode in a position apart from the insulating substrate, impressing a voltage of the polarity reverse from the normal electrostatic charging polarity of the toners to this common electrode for a short time and instantaneously floating the toners stagnated at the disconnected electrode for electrostatic conveyance among the electrode trains of the electrostatic conveyance during the electrostatic conveyance of the toners toward the common electrode.;COPYRIGHT: (C)2003,JPO
