Apparatus and method for optimizing image transfer environment in an electrophotographic system

摘要

An apparatus and a method for optimizing an image transfer environment in an electrophotographic developing device is provided. The apparatus includes at least one or more discharging parts disposed on a printing path, contacting with a printing paper as it is fed, for discharging electrostatic electricity formed on the printing paper; a feeder roller made of a conductive material, for electrically detecting an amount of humidity contained in the printing paper and for feeding the printing paper between the transfer roller and the photosensitive drum; and a ground controller for selectively controlling connection or disconnection of the at least one or more grounds based upon the humidity amount input from the feeder roller to the ground controller.
