Abstract:
An image forming apparatus which records an image on a recording medium by scanning the recording medium with a plurality of beams modulated according to individual information signals, comprising:a beam detect device to detect the plurality of beams arriving at the beam detect device, and to generate a plurality of beam detect signals corresponding to the plurality of beams respectively;a beam detect signals separating device to separate the plurality of beam detect signals into individual beam detect signals; anda control device to turn off a first beam of the plurality of beams incident on the beam detect device and to turn on a subsequent beam of the plurality of beams, immediately after the first beam is detected by the beam detect device,wherein, an image formation start timing for each beam is controlled by said control device according to each beam detect signal separated from others by the beam detect signals separating device.
