Abstract: A method and apparatus for maintaining the air pressure within a xerographic module (1) of an image forming device above the ambient pressure outside of the xerographic module (1). A pressure sensor, (e.g., an altimeter) is used to monitor ambient atmospheric pressure, and a controller maintains the air pressure at a determined set point or within a determined range so that the risk of contaminants entering the xerographic module (1) and adversely affecting its internal elements is reduced.

Abstract: PROBLEM TO BE SOLVED: To provide a system for keeping the pressure inside the electrophotographic module/chamber of an image forming device in the specified range. SOLUTION: This image forming device has the electrophotographic module 1 arranged in the chamber having the pressure made higher than the ambient atmospheric pressure by pressurization.
