Abstract

An image forming apparatus includes a photoreceptor that has a surface layer in which a transmittance of light having a wavelength of 1,000 nm is 5% or more and 95% or less, a charging device that charges a surface of the photoreceptor, an electrostatic latent image forming device that forms an electrostatic latent image on the charged surface of the photoreceptor, a developing device that develops the electrostatic latent image formed on the surface of the photoreceptor with a developer containing a toner to form a toner image, a transfer device that transfers the toner image to a surface of a recording medium, and a photoreceptor cleaning device that has a cleaning blade coming into contact with the surface of the photoreceptor to clean the surface of the photoreceptor, in which a contact portion of the cleaning blade coming into contact with the photoreceptor contains a polyurethane rubber that is obtained by polymerizing at least a polyol component and a polyisocyanate component, a ratio M100/Re of a 100% modulus M100 (MPa) to an impact resilience coefficient Re (%) is 0.25 or more, the impact resilience coefficient Re is less than 25%, and a tensile stress with a 200% strain at a temperature of 23°C is 15 MPa or more.
