Abstract
The present invention relates to a corona discharger displacing mechanism and a grid electrode positioning mechanism which are used for a unit of an image forming section in an image forming apparatus. The displacing mechanism causes a corona discharger to advance or retreat in synchronism with the inserting or extracting operation of the unit. On the other hand, the positioning mechanism stretches a grid electrode in co-operation with the unit.
