Image forming apparatus

An image forming apparatus comprising:

• an electrophotographic photoreceptor that is provided with a photosensitive layer and an overcoat layer on an electroconductive substrate in this order;
• a charge unit that charges a surface of the electrophotographic photoreceptor;
• an electrostatic latent image forming unit that forms an electrostatic latent image on a charged surface of the electrophotographic photoreceptor;
• a developing unit that contains a developer containing toner particles, and develops the electrostatic latent image formed on the surface of the electrophotographic photoreceptor with the developer to form a toner image;
• a transfer unit that transfers the toner image to a surface of a recording medium;
• a cleaning unit that includes a cleaning blade and a tip of the cleaning blade contacts with the electrophotographic photoreceptor toward the direction opposite to a rotation direction of the electrophotographic photoreceptor to remove a residue on the surface of the electrophotographic photoreceptor;
• and
• a fixing unit that fixes the toner image transferred on the recording medium,
• wherein the toner particle contains a binder resin containing a crystalline polyester resin, a colorant, and a release agent,
• an average circularity of the toner particles is from 0.955 to 0.971,
• a content ratio of the toner particles having a particle diameter of 4.5 μm or more and less than 7.5 μm and a circularity of 0.980 or more is in a range of 16% by number to 40% by number, and
• a content ratio of the toner particles having a particle diameter of 7.5 μm or more and less than 15 μm and a circularity of 0.900 or more and less than 0.940 is 3% by number or less.
