<P>PROBLEM TO BE SOLVED: To provide an image forming device which can form an image without reducing a speed even when dew condensation occurs. <P>SOLUTION: When a pseudo signal is generated by a lighting control circuit, a dew condensation determination program determines high possibility of dew condensation on a BD sensor, and an abnormality determination program determines abnormality in the BD sensor, a lighting start timing of a light-emitting element is controlled by using the pseudo signal instead of a BD signal. <P>COPYRIGHT: (C)2012,JPO&INPIT |
