摘要： An optical writing head positioning mechanism includes spacers provided between a latent image carrier for carrying an electrostatic latent image and an optical writing head for exposing the latent image carrier. The spacers each include at least one carrier contact surface that contacts the latent image carrier and at least one head contact surface that contacts the optical writing head to determine an interval between the latent image carrier and the optical writing head. The latent image carrier is in contact with a cleaning member that cleans a cleaning area on a surface of the latent image carrier. In at least one of the spacers, the at least one carrier contact surface includes plural carrier contact surfaces not disposed on edges of the cleaning area, and one of the edges of the cleaning area is located between two adjacent ones of the plural carrier contact surfaces.
