Abstract
An image forming apparatus includes a photoreceptor; a charging device that charges a surface of the photoreceptor; an electrostatic latent image forming device that forms an electrostatic latent image on the surface of the photoreceptor; a developing device that contains a developer containing a toner and develops the electrostatic latent image formed on the surface of the photoreceptor to form a toner image; a transfer device that transfers the toner image to a surface of a recording medium; and a 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 the photoreceptor has an inorganic surface layer containing a Group 13 element and an oxygen element, the cleaning blade has an impregnated cured layer of an isocyanate compound and a silicone-modified acrylic polymer at a contact portion in contact with the surface of the photoreceptor, a 100% modulus of the cleaning blade is 13 MPa or more and 22 MPa or less, a tip angle of the cleaning blade is 60 degrees or more and 87 degrees or less, and an action angle of the cleaning blade with respect to the surface of the photoreceptor is 8 degrees or more and 30 degrees or less.
