Abstract

PURPOSE: To prevent the deterioration of a sleeve, eliminate image unevenness and improve image quality by so controlling a toner-removing scraper that it does not contact the sleeve during developing.
CONSTITUTION: A stay 8 is provided to a scraper 5 on the side opposite from a sleeve 2, and this stay 8 is turned by a driving source 9 such as motor. When it is turned clockwise, it maintains a contact working state as shown by the solid lines and when turned counterclockwise, it maintains a noncontact dwell state. These make it possible to prevent the deterioration of the sleeve by using the scraper; moreover, head image unevenness may be eliminated and the image quality may be improved.
