ELECTROPHOTOGRAPHIC PRINTING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an electrophotographic printing device by which excellent printing quality is always maintained whatever width continuous paper to be used has. SOLUTION: When the width of the continuous paper to be used is smaller than the corona discharge length of a corona discharge device for recovering a toner electrifying polarity, an insulating member is arranged at a part where the continuous paper does not exist and the mutual wires of two corona discharge devices for recovering the toner electrifying polarity are directly opposed between the two opposing corona discharge devices. When the width of the continuous paper to be used is changed, the length of the insulating member is changed in accordance with the width thereof.
