The image forming apparatus including: a photoconductor provided with a charge generation layer and an overcoat layer; a first charging unit charging the photoconductor when an image is formed; an exposure unit irradiating the photoconductor with light having a wavelength to which a relative sensitivity of the charge generation layer is larger than a relative sensitivity of the overcoat layer; a development unit developing an electrostatic latent image formed on the photoconductor by the first charging unit and the exposure unit with toner; a transfer unit transferring an image developed on the photoconductor to a medium; a light irradiation unit irradiating the photoconductor with light having a wavelength to which the relative sensitivity of the overcoat layer is larger than the relative sensitivity of the charge generation layer; and an erasing unit erasing a charge from the photoconductor irradiated with light by the light irradiation unit.
