Abstract
PURPOSE: To prevent the occurrence of separation discharge by providing a charger which does corona discharge of a polarity opposite to that of transferring time adjacent to the transfer charger which faces each photosensitive drum for each color.
CONSTITUTION: Each color image processed and developed by photosensitive drums 3, 3, 3 of each color is transferred on transfer paper 7 transported by corona discharge of transfer chargers 8, 8, 8. The potential of the transfer paper which has been raised to the high potential at the time of transferring is neutralized by corona discharge due to chargers 9, 9, 9 disposed adjacent to chargers 8, 8, 8 and by corona discharge of opposite polarity due to chargers 8, 8, 8 to reduce the voltage of separation discharge. Therefore the separation discharge will not be produced at the time of high humidity, hence the occurrence of non-uniform multicolor image due to the separation discharge is prevented.
