Patent ID: 8447222

Claim:
An image forming device, comprising: a plurality of image forming units each including: a developer carrier that carries developer; an image carrier that forms an electrostatic latent image by being charged by a charge device and exposed to an exposure device, and that forms a developer image on a surface layer by attaching the developer supplied from the developer carrier onto the electrostatic latent image formed thereon; and a developer collector that is positioned to contact the surface layer of the image carrier and that removes residual developer after transferring the developer image formed on the surface layer onto a recording sheet, wherein the developer collector in a first image forming unit has a higher linear contact pressure against the surface layer of the image carrier than that of other image forming units, and a thickness of the surface layer of the image carrier of the first image forming unit is greater than a thickness of the surface layer of the image carrier of the other image forming units.
