Apparatus for and method of recording image

An apparatus for recording an image by scanning a photosensitive medium which is fed in an auxiliary scanning direction, with a light beam generated based on an image signal in a main scanning direction substantially perpendicular to said auxiliary scanning direction, comprising:

• present recording duty cycle detecting means for detecting a present recording duty cycle of an image to be recorded on the photosensitive medium based on the image signal;
• light beam intensity modulating means for modulating the intensity of the light beam based on the detected present recording duty ratio;
• preceding recording duty cycle detecting means for detecting a preceding recording duty cycle of the image at a position scanned later than said present recording duty cycle detecting means in the main scanning direction;
• and
• intensity modulation correcting means for comparing the detected preceding recording duty cycle and the detected present recording duty cycle to correct the modulation of the intensity of the light beam with said light beam intensity modulating means.
