Image forming method and an image forming apparatus

A color image forming method comprising:

• developing latent images each for a black toner image, yellow toner image, cyan toner image and magenta toner image, and each formed on a predetermined cylindrical electrophotographic photoreceptor having a cylindricity of 5 to 40 μm, with a yellow toner, a cyan toner, a magenta toner and a black toner corresponding to the latent images, wherein at least one of the toners has a ratio Dv50/Dp50 of a 50% volume particle diameter Dv50 to a 50% number particle diameter Dp50 being 1.0 to 1.15, a ratio Dv75/ Dp75 of a cumulative 75% volume particle diameter from the largest volume particle diameter Dv75, to a cumulative 75% number particle diameter from the largest number particle diameter Dp75, being 1.0 to 1.20, and the number of toner particles having a particle diameter of 0.7×Dp50 or less, each of the toners is provided from each one of development devices;
• transferring the either yellow, magenta, cyan of black toner images from the predetermined cylindrical electrophotographic photoreceptor to an intermediate transferring member, and
• supplying a surface energy lowering agent to the predetermined cylindrical electrophotographic photoreceptor from a surface energy lowering agent supplying device, wherein the, predetermined cylindrical electrophotographic photoreceptor has a layer which contacts at least one of the toners in the developing step, and the layer has inorganic particles having a number average primary particle diameter of 1 nm to less than 100 nm.
