A laser beam printer comprises a single scanner deflecting a plurality of laser beams for the purpose of scanning, a laser beam position detector detecting the position of one of the deflected laser beams, and a plurality of delay circuits determining the recording starting timing of the plural laser beams in response to the output signal from the laser beam position detector. The surface of a photosensitive drum is scanned with the plural laser beams to sequentially form a plurality of electrostatic latent images corresponding to a plurality of predetermined colors respectively, and the latent images are sequentially developed with a plurality of color toners during one rotation of the photosensitive drum. The color toner images are simultaneously transferred onto a recording sheet to obtain a record printed in plural colors.
