METHOD FOR CONTROLLING PRESSURIZATION OF SQUEEZING ROLLER OF IMAGE FORMING DEVICE

PURPOSE: A method for controlling pressurization of a squeezing roller of an image forming device is provided to reduce driving load of a motor and maintain constant speed driving of a photosensitive belt in pressurizing a squeezing roller and contacting the squeezing roller with the photosensitive belt. CONSTITUTION: A method for controlling pressurization of the squeezing roller of the image forming device includes the steps of performing squeezing motion by pressurizing squeezing rollers(111d) contained in Y, M, C and K color developing devices under a first step pressure, and performing squeezing motion by pressurizing another squeezing roller(301) disposed at the rear portion of K color developing device under a second step pressure, which is higher than the first step pressure.
