主权项 1. An electrophotographic image forming method, comprising: charging the surface of an electrophotographic photoreceptor; irradiating the surface thereof with imagewise light to form an electrostatic latent image; developing the electrostatic latent image with a toner to form a toner image; transferring the toner image onto a recording medium; fixing the toner image thereon; and applying an overcoat composition onto the toner image, wherein the overcoat composition comprises at least one of compounds having the following formulae (2) or (3): wherein R1 represents a hydrogen atom or a methyl group; and n represents an integer of from 4 to 6; and wherein R1 represents a hydrogen atom or a methyl group; and a and b independently represent an integer of from 1 to 5 on the condition that a+b is from 4 to 6.
