Abstract:
An image forming apparatus, comprising:a belt-shaped carrier supported for movement on a drive roller, multiple idler rollers and a tension roller; a latent image forming apparatus mounted on said belt shaped carrier; a developing apparatus for applying toner on a latent image formed by said latent image forming apparatus on said belt-shaped carrier; and a transfer apparatus for transferring the toner image formed by said developing apparatus; wherein, when a path leading from said drive roller to said tension roller in a forward direction of movement of said belt-shaped carrier is defined as a drive roller downstream path, and a path leading from said tension roller to said drive roller is defined as a drive roller upstream path, the amount of eccentricity of any idle roller located on said drive roller downstream path is made smaller than that of the idle roller located on said drive roller upstream path, and wherein said latent image forming apparatus is arranged on said drive roller downstream path.
