A multibeam laser apparatus for an image forming device, includes a common electrode unit (130), a plurality of light source units (260,270,280,290) to emit light using the common electrode unit (130), and an isolating unit (220) to interconnect the common electrode unit (130) and the plurality of light source units (260,270,280,290), the isolating unit (220) being provided with grooves of different depth and/or different concentrations of a dopant in accord with distance to the common electrode. Such configuration can reduce distances between the respective light source units, the number of the electrodes and, thus, the number of wires and legs to produce a compact chip without crosstalk. |
