Abstract
The invention relates to a method and an apparatus with which a powdered developer deposited onto a sheet of paper can be fixed. The method comprises moving the sheet in such a manner that its leading edge (BV) comes to face a source (47) integral with a movable support, initially placed in a position of repose, and then, after immobilization of the sheet, displacing the support over a distance (N) less than the length (L) of the sheet, and moving the support to the position of repose while simultaneously displacing the sheet in the same direction, at a speed greater than the speed of the support. The invention is applicable to magnetic printing machines.
