BELT UNIT OF ELECTROPHOTOGRAPHIC PRINTER

摘要

PROBLEM TO BE SOLVED: To prevent that a belt is damaged and becomes unusable caused by insertion of a belt unit since the belt unit is inserted into an electrophotographic printer main body without returning a position of a cum to a position at the time of actual printing when variation of belt perimeter is large, when a loading position of the belt in the width direction is indefinite and after loading the belt in the belt unit. SOLUTION: A blade for cleaning the rear surface of the belt is mounted on the belt unit and a guide for loading belt having a rotating shaft is provided in the belt width direction. In addition, the guide for loading belt is constituted so that it has an edge inclined to the rotating shaft, has level difference for specifying the width direction in the case that the belt travels at the time of actual printing in one end part of the width direction and is located higher than a frame for forming an insertion part owned by a printer main body when the belt is loaded.
