Patent ID: 8511680

Claim:
An image forming device comprising: a main body including a pair of main frames made of metal; a plurality of photosensitive members arrayed in a predetermined direction in the main body and disposed between the pair of main frames; a first frame attached to each of the pair of main frames and made of a first resin with a higher linear expansion coefficient than the metal of the pair of main frames; a second frame attached to each of the pair of main frames and made of a second resin with a higher linear expansion coefficient than the metal of the pair of main frames; a conveying section supported by each of the first frames so as to confront the plurality of photosensitive members, the conveying section being made of a third resin with a linear expansion coefficient that is higher than that of the metal of the pair of main frames and lower than that of the resin of the first frames and the second frames; an input section provided to the conveying section for transmitting a driving force to the conveying section, wherein the conveying section conveys a recording medium upon receiving the driving force through the input section; and an output section supported by at least one second frame and linked to the input section, the output section being configured to transmit the driving force to the input section.
