Zusammenfassung:	PURPOSE:To execute the automatic adjustment of irregularities in a density in the axial direction of a light source, with high accuracy by correcting an image density changed by the characteristics of the light source with the temp. of a photosensitive sheet at the time of exposure-processing. CONSTITUTION:A sensitivity information sensor S1 is provided on the upstream side of exposing base. The sensor S1 is composed of an optical sensor, and reads the characteristics of the mounted photosensitive sheet 4. A microcomputer sets the target temperatures of each heater wire, based on the inputted image density and the temp. dependency of the sensitivity of the photosensitive sheet read by the sensitivity information sensor S1. At this time, the target temp. of each heater wire is set so that the irregularities in the image density in the axial directions of the light sources 2a and 2b are corrected.
