摘要： A control device (10) includes an acquirer (32), a timing detector (33), a controller (30), and a driver (31). The acquirer (32) is configured to acquire an output voltage from a light detector (16) for receiving laser light scanned by a light source (12) and a deflector (13). The timing detector (33) is configured to detect reference timings of the laser light on forward and backward paths in a scanning direction based on the output voltage. The controller (30) is configured to generate a control signal for causing the light source (12) and the deflector (13) to draw a forward path image on a scanned surface from time obtained by adding a time to the reference timing on the forward path and to draw a backward path image on the surface from time obtained by adding a time to the reference timing on the backward path. The driver (31) is configured to draw the images by driving the deflector (13), based on the control signal.
