Abstract
An image forming apparatus includes a rotatable image bearer, a charging member to contact a surface of the image bearer and charge the image bearer, an exposure device to expose the image bearer and form a latent image, a developing device to develop the latent image on the image bearer into a toner image, a transfer device to transfer the toner image from the image bearer onto a transfer medium, and a cleaning blade to contact the surface of the image bearer and remove toner from the image bearer after image transfer. The charging member has surface unevenness created by projections and recesses extending in a direction of rotation of the image bearer. The cleaning blade is configured to abrade projections formed on the surface of the image bearer.
