PURPOSE: To establish an image forming method presenting good reproducibility for thin line, durability, and cleaning performance and provide a simplified and small-sized device for forming a multi-color image.
CONSTITUTION: A toner is prepared from a stylene-acrylic acid copolymer at least not having a common bond type bridge structure and a pigment, wherein the volume-averaged particle size of the toner particles ranges from 5 to 9μm, and the value of relation (Dp50)2/(Dp25) is between 3.90-4.9g, where Dp25 represents the 25% cumulative value from the greater side in the particle side distribution and Dp50 represents the corresponding 50% cumulative value. In this transfer image forming method where the described electrophotographic toner is used, the toner remaining upon an organic sensitive substance is cleaned by the use of blade.
