Abstract
An image forming apparatus includes: a photoconductor; a charger configured to charge the photoconductor, the charger having a discharge wire and a grid; a charge-voltage applying device configured to generate charge voltage and apply the charge voltage to the discharge wire; and an abnormal-discharge detector provided between an output end portion of the charge-voltage applying device and the ground. The abnormal-discharge detector is configured to detect an abnormal discharge occurring in the charger by detecting an abnormal current passing via the grid and the ground upon occurrence of the abnormal discharge.
