Abstract

A separating agent metering device (30) contains a separating agent feed roller (1) which rolls tangentially against the fuser roller (8). In doing so, separating agent from the inside of the separating agent feed roller (1) which has passed to the surface is transferred to the fuser roller (8). The separating agent feed roller (1) contains a carrier tube (6), which is rotatably mounted on a separating agent metering tube (5), and an applicator roller (7) which is arranged on said carrier tube so as to be exchangeable. The applicator roller (7), which contains an applicator sleeve (4) with a layer of material (13) which is permeable to the separating agent attached thereto, can be slid axially over the carrier tube (6).
