PRINTER AND PHOTO SCAN TIME CONTROL METHOD THEREOF

PURPOSE: A printer and a photo scan time control method thereof are provided to control a scan time of each photo unit corresponding to a speed change of a photosensitive belt. CONSTITUTION: Brush rollers(22,32,42,52) clean developing agents remaining at developing rollers(21,31,41,51). Squeeze rollers(23,33,43,53) remove a carrier element in a liquid phase remaining on a photosensitive belt(11). A developing agents supply section supplies developing agents stored in a receptacle between the photosensitive belt(11) and developing rollers(21,31,41,51). Encoders(81-83) detect and output rotating amount of squeeze rollers(23,33,43) to a controller(90). The controller(90) obtains a section speed information based on rotating amount information of squeeze rollers(23,33,43) output from the encoders(81-83).
