Abstract
An image forming apparatus includes a rotatable image carrier, a charging roll and a support member. The image carrier has a surface on which an electrostatic latent image is to be formed. The charging roll follows rotation of the image carrier. The charging roll charges the surface of the image carrier at a predetermined potential. The support member is in contact with the charging roll at a contact point. The contact point is on a downstream of a nip portion between the image carrier and the charging roll in a rotation direction of the charging roll. The contact point is on an upstream of a plane, which contains an axis line of the charging roll and is perpendicular to a plane defined by an axis line of the image carrier and the axis line of the charging roll.
