Abstract
The invention provides a neutralization apparatus which simplifies an apparatus composition, lowers an apparatus cost and removes electrical charge effectively from a ribbon-like substance which is charged by stripping, and provides a printer having the neutralization apparatus. The neutralization apparatus neutralizes an ink ribbon. The neutralization apparatus has a conductive roller which is arranged so as to contact the surface of the ink ribbon and a neutralization brush which counters the back of the ink ribbon. A balance of the electrical charge of the surface and the electrical charge of the back of the ink ribbon is broken by electrical discharge caused by the conductive roller. And thereby, the charged voltage of the electrical charge of the back of the ink ribbon becomes large and the neutralization brush remove the electrical charge charged to the back of the ink ribbon effectively.
