Claim:
An image forming device comprising: an endless belt forming a loop-shaped path of movement passing over between a drive roller and an idle roller that are fixed at positions in the device; a plurality of image bearing members disposed side by side within predetermined limits along a direction of movement of the endless belt, each of the plurality of image bearing members bearing a toner image of a different hue; and a plurality of transfer members disposed on an inner side of the path of movement at positions of respective downstream sides of the plurality of image bearing members in the direction of movement so as to oppose the plurality of respective image bearing members sandwiching a part of the endless belt in between, each of the plurality of transfer members transferring onto the endless belt a toner image borne on each of the plurality of image bearing members, wherein: a position in which the image bearing member disposed on the most upstream side in the direction of movement of the endless belt contacts the endless belt coincides, in the direction of movement of the endless belt, with a position in which the opposed transfer member contacts the endless belt, whereas a position in which each of the other image bearing members contacts the endless belt is offset, in the direction of movement of the endless belt, from a position in which the opposing respective transfer member contacts the endless belt; and a hue of a toner image borne on the image bearing member disposed on the most upstream side in the direction of movement is yellow.
