Abstract
An image forming apparatus, including: a photoconductor configured to be rotatable; a charger configured to charge the photoconductor; an overcurrent detector configured to output an overcurrent detection signal in response to detection of an overcurrent in the charger; and a controller, wherein the controller is configured to execute: an obtaining process of obtaining the overcurrent detection signal output from the overcurrent detector; a first counting process of counting a first number of detections based on the overcurrent detection signal obtained in the obtaining process, the first number of detections being the number of the overcurrent detection signals synchronized with a first cycle corresponding to one rotation of the photoconductor; and a first determining process of determining whether the first number of detections is not smaller than a first threshold which is not smaller than 2.
