Abstract

Eine Vorrichtung zum Entwickeln eines elektrostatischen Bildes zeichnet sich aus durch eine Fotoleitertrommel (12)) und eine Magnetbürste (14) in Kontakt mit der Fotoleitertrommel (12), die eine Mischung (52) aus Toner und hartmagnetischen Trägerpartikeln auf die Fotoleitertrommel (12) aufbringt. Des weiteren umfasst ein Träger für eine Tonereinheit (10) eine Stützschiene (102), eine Gleitschiene (104), die in der Stützschiene (102) liegt, wobei die Gleitschiene (104) so angepasst ist, dass sie die Tonereinheit (10) aufnimmt, ein Paar Passstifte (56), wobei die Gleitschiene (104) die Tonereinheit (10) im Verhältnis zu den Passstiften (56) positioniert und ein Stellglied (114), das die Tonereinheit (10) in Registerhaltigkeit mit den Passstiften (56) bringt.
