Abstract
A color printer includes a conveyer belt for conveying a paper sheet to make the sheet pass through a plurality of photoconductive drums. A suction roller for sucking a supplied paper sheet on the conveyer belt is provided on the upstream side of the photoconductive drums in the conveying direction of the paper sheet, such that the suction roller is in rolling contact with the belt. Transfer chargers are provided at positions opposing the photoconductive drums, respectively, with the conveyer belt situated between the drums and the transfer chargers. The running distance L1 (mm) of the conveyer belt from a sheet peeling position corresponding to the photoconductive drum at the rearmost position to a suction position where the suction roller is provided, the volume resistance .rho. (.OMEGA..multidot.cm) of the belt, and the relative dielectric constant .epsilon. of the belt are set so as to satisfy a relation of L1/V.gtoreq.(.epsilon..multidot..epsilon..sub.0 .multidot..rho.).times.7.
