PURPOSE: To always execute printing of an appropriate color scheme by suppressing the variance of the light intensity between each light so that the variance between each of plural monitoring output signals becomes within a range set in advance.
CONSTITUTION: The title device is provided with a circuit 45 for obtaining plural monitoring output signals by monitoring the light intensity of each light by light intensity detectors 43AW43D at the time of recording the information to a photosensitive body by plural rays of light, and adjusting the light intensity of each light so that the deviation of other monitoring output signal at the time when an arbitrary one of these plural monitoring output signals is set as a reference is contained within a range set in advance. In such a way, the variance of the light intensity between each light is suppressed and the output of beam for information recording can be stabilized.
