Abstract
An image forming apparatus comprises a conveyance section, a plurality of sensors, an image forming section, a conveyance control section and a control section. The conveyance section forms a conveyance path for conveying paper. The plurality of sensors outputs detection signals indicating the existence of the paper at a plurality of positions along the conveyance path. The image forming section forms images on the paper conveyed by the conveyance section. The conveyance control section controls the conveyance of the paper conveyed by the conveyance section based on the detection signals of the plurality of sensors. The control section determines, in a case in which the detection signal of any of the plurality of sensors is abnormal, whether it is due to sensor failure or paper conveyance abnormality, and sets to ignore the detection signal of the failed sensor and continue the processing if it is due to the sensor failure.
