Abstract
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, wrapping roller, and transfer unitsandare arranged so that a line La connecting a center Ca of a rollerand a transfer point Ta and a line Lb connecting a center Cb of a rollerand 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 photoconductorsandis specified to 5 mm≦W≦25 mm, even when a wrapping roller is not arranged between printing unitsand, a fixed wrapping width of the form S around the belt photoconductorsandis reserved.
