Patent ID: 7220526

Claim:
An image forming method comprising: forming a latent image on a cylindrical electrophotographic photoconductor including a mass additive therein; and developing the latent image, with a developer comprising a toner, wherein the toner has (1) a ratio (Dv50/Dp50) of a 50% volume particle size (Dv50) to a 50% number particle size (Dp50) of 1.0 to 1.15, (2) a ratio (Dv75/Dp75) of a cumulative 75% volume particle size (Dv75) from a larger volume particle size to a cumulative 75% number particle size (Dp75) from a larger number particle size of 1.0 to 1.20, and (3) toner particles having a particle size of 0.7×(Dp50) or less in an amount of 10 number % or less.
