ABSTRACT:
In a multi-beam scanning device including a laser diode array having three or more light emitting points, the interval Pi between one of the three or more light emitting points and the adjacent light emitting point is set so as to be not greater than the minimum recording interval Pi′ of image information to be recorded on a recording medium. In addition, the three or more light emitting points are arranged such that the corresponding laser beam spots formed on the recording medium are arranged in a line or substantially in a line in the sub-scanning direction B. Thereby recording speed and recording density can be increased.
