Abstract
An image forming apparatus includes a charger for charging a photosensitive drum, the charger having a charging wire extending in a lengthwise direction of the photosensitive drum, an optical system for illuminating a document and introducing a reflected light to the photosensitive drum to produce a latent image of the document, a detector for detecting a target portion of the charging wire causing a white line based on a copied image on copy paper, a cleaning member movable along the charging wire and adapted for cleaning the charging wire, a driver for moving the cleaning member along the charging wire, and a controller responsive to the detector for controlling the driver to move the cleaning member to the target portion of the charging wire and clean the target portion.
