PROBLEM TO BE SOLVED: To arbitrarily control the arriving light quantity of split laser light onto a face to be scanned. SOLUTION: The laser scanner comprises: LD1a and 1b which generate laser light; a light source light quantity control part 110 which variably controls the light emission quantity of the LD1a and 1b; a polygon mirror which deflects and scans the laser light from the LD1a and 1b; a half-mirror prism which splits the passing paths of the laser light; and a first scanning lens, a mirror and a second scanning lens which condense and scan the split laser light onto a plurality of photoreceptor faces, wherein the light source light quantity control part variably controls the light emission quantity of the LDs on the basis of laser light emitted light quantity correction data stored in a storage part 130 corresponding to the scanning positions of the plurality of photoreceptor faces.
