ABSTRACT:
A color image recording apparatus for producing a composite color image on a paper sheet by developing electrostatic latent images formed on a photoconductive element, which is implemented as a belt, in different colors. The belt is supported and driven in a rotary motion by at least two rollers, i.e., a drive roller and a tension roller. The drive roller is fixed in place at a transfer station, while the tension roller is situated downstream of an exposure station with respect to the intended direction of rotation of the belt, i.e., at a developing station side. More specifically, the tension roller is so positioned as not to be effected by a change in the configuration of the belt ascribable to the selective content of developing rollers of individual developing units with the belt. The length of the belt as measured from the exposure station to the transfer station is maintained constant. The belt moves at the same speed at both of the exposure station and transfer station.
