Abstract
Preheating temperature of a preheating plate provided on the front side of a fixing unit can be changed using a temperature controller. In a case where a printing system to print images on both sides of a print member is constructed by arranging two electrophotographic printing apparatuses in dependent relationship, the preheating temperature of the preheating plate in the electrophotographic printing apparatus in the second stage is changed to a low temperature to prevent the toner image fixed in the electrophotographic printing apparatus in the first stage from softening.
