IMAGE FORMING DEVICE AND PRODUCTION OF INTERMEDIATE TRANSFER BELT USED FOR THE SAME

Japanese Patent JP3248455

B2

PROBLEM TO BE SOLVED: To provide an image forming device capable of obtaining a high- quality image without the scattering of toner at the time of performing a transfer, without the need of a static charge removal mechanism and of preventing the generation of the hollow character.
SOLUTION: In an image forming device, an electrostatic latent image formed on an image carrier 1 is turned into a visible image by a developing device 4, and the toner image on an intermediate transfer belt 7 is secondarily transferred to a recording medium P by a bias roll 10 after being primarily transferred. The intermediate transfer belt is structured with at least two layers; that is, a base material which consists of a material excellent in a mechanical characteristic such as polyimide resin and has a Young's modules of ≥35000 kg/cm2, and a surface layer which consists of a material whose surface energy is small such as fluororesin, and whose volume resistivity is within the range of 1010-1013 Ω.cm. When the intermediate transfer belt is structured with three layers, it is preferable that an intermediate layer consists of an elastic material or a material whose surface layer has a Young's modulus of ≤15000 kg/cm2, as an adhesive layer.
