ABSTRACT:
A color printer has four photoconductive drums and image forming sections provided corresponding to the drums, for forming images on the drums, respectively. A conveyor belt device has an endless belt which is stretched between a driving roller and a driven roller so as to convey a paper sheet in sequence to the drums. A regulation plate is arranged opposite to one end face of the driving roller, and slides in contact with one side edge of the conveyor belt. If a thickness of the conveyor belt is t (mm), a width of the conveyor belt in the axial direction of the driving roller is Bw (mm), a vertical elasticity coefficient in a width direction of the conveyor belt is E (g/mm.sup.2), a load applied to the conveyor belt to stretch the conveyor belt is W (g/mm), and a diameter of the driving roller is D (mm), a distance L (mm) between the regulation member and the one end face of the driving roller is set so as to satisfy a following relationship:
