IMAGE WRITING UNIT AND IMAGING APPARATUS

摘要

PROBLEM TO BE SOLVED: To obtain a high quality image even in the case of divided exposure to a photosensitive layer of a photosensitive member by a plurality of light emitting element array units. SOLUTION: An image writing unit comprises a plurality of LED heads (light emitting element array units) 503 disposed zigzag along the axis direction of a photosensitive member (main scanning direction). An LED writing controlling circuit 501 transmits image data (image information) to the LED heads 503 while dividing the same for each LED head 503 and lagging the time for a focusing position in the photosensitive member rotation direction. At the time, according to the temperature detected by a thermistor (temperature detecting means) provided in the inside of or in the vicinity of each LED head 503, the light emitting amount of either one or both of two light emitting elements disposed at the joint of the LED heads 503 corresponding to a part of or the entirety of an image data dividing position is corrected.
