<Cause>
This problem occurs when paper moves between the photosensitive drum and the transfer roller. When the
photopositive surface comes close to or into contact with the toner-coated surface of paper, the toner layer can
become shifted toward the trailing edge of the paper. This problem tends to be conspicuous when the toner layer is
relatively high against the width of lines (about 0.2 to 0.6 mm) and, in addition, when the lines are at a right angle to
the feed direction (axial direction of the photosensitive drum).
