Abstract:
1. An image forming apparatus comprising: an exposure component that is equipped with a plurality of independently drivable light emitting elements arrayed along a first direction and which exposes photoconductors by scanning, in a second direction intersecting the first direction, light that is emitted when the light emitting elements are driven by drive signals based on image data; an output component that is equipped with output ends corresponding to each of the light emitting elements and which, at normal times, outputs, one line at a time, drive signals of plural lines when exposure is performed in one scan by the exposure component from each of the output ends and which, when correcting an amount of misalignment in the first direction, outputs drive signals of one line corresponding to a line on a most upstream side of drive signals of plural lines from the output ends that have been shifted by a number corresponding to the amount of misalignment in the first direction; a plurality of connecting wires that interconnect each of the output ends of the output component and each of the light emitting elements of the exposure component; a selection component that selects at least one of the connecting wires that is connected to output ends, from among the output ends, that output the drive signals corresponding to the line on the most upstream side and a line that is exposed by a same scanning as a scanning by which the line on the most upstream side is exposed, when correcting the amount of misalignment in the first direction; and a judging component that is connected to each of the connecting wires, and judges whether or not the drive signals are being normally transmitted through the at least one of the connecting wires selected by the selection component.
