Patent ID: 7826783

Claim:
An image forming device, comprising: an image support body on which an electrostatic latent image is formed; a developer which develops the electrostatic latent image formed on the image support body with a toner to form a toner image; an intermediate transfer belt onto which the toner image formed on the image support body is transferred; a primary transfer means for transferring the toner image on the image support body onto the intermediate transfer belt; and a secondary transfer means for transferring the toner image on the intermediate transfer belt onto paper, the image support body and the primary transfer means being offset placed, wherein a volume resistance of the intermediate transfer belt is adjusted to a value within the range of from 1×10 7 to 1×10 11 Ω·cm and a surface resistance of the intermediate transfer belt is adjusted to a value within the range of from 1×10 8 to 1×10 12 Ω/□, and wherein the intermediate transfer belt is constituted by a resin composition including a polyamide resin, a thermoplastic elastomer and an electroconductive material, and an addition quantity of the thermoplastic elastomer is adjusted to a value within the range of from 10 to 150 parts by weight based on 100 parts by weight of the polyamide resin and an addition quantity of the electroconductive material is adjusted to a value within the range of from 0.1 to 100 parts by weight based on the amount of resin composition.
