An image forming apparatus capable of preventing contamination of a brush-roller charger with toner depositions includes a photoconductor, a brush-roller charger, an image development mechanism, an image transfer mechanism, a cleaning mechanism, a power supply mechanism, and a controller. The photoconductor carries an electrostatic latent image thereon. The brush-roller charger rotates in contact with the photoconductor and initializes a surface of the photoconductor by applying a charge thereto. The image development mechanism contacts the surface of the photoconductor and supplies toner to develop a toner image according to the electrostatic latent image on the surface of the photoconductor. The image transfer mechanism transfers the toner image from the photoconductor to a recording sheet. The cleaning mechanism cleans the surface of the photoconductor. The power supply mechanism supplies power to the brush-roller charger. The controller controls the power supply mechanism to stop supplying a voltage to the brush-roller charger for a predetermined time period required for the brush-roller charger to rotate at least one rotation after an image forming operation is finished and before a following image forming operation is started.
