To provide a printer capable of minimizing the effect of a wrapping member, which is used for wrapping a recording form around a photoconductor, on image quality and realizing high image quality printing, a conveying roller 6, wrapping roller 8, and transfer units 36a and 36b are arranged so that a line La connecting a center Ca of a roller 38a and a transfer point Ta and a line Lb connecting a center Cb of a roller 38b and a transfer point Tb are inclined to a central line A-A and are almost symmetric to the central line A-A. When the wrapping width W of the form around belt photoconductors 32a and 32b is specified to 5 mm.ltoreq.W.ltoreq.25 mm, even when a wrapping roller is not arranged between printing units 30a and 30b, a fixed wrapping width of the form S around the belt photoconductors 32a and 32b is reserved.
