Abstract (en)
[origin: WO8908285A1] To prevent entrainment of the mixture in the development region of an electrophotographic printing device, the mixture carpet is guided to the development gap so that the mixture carpet (23) in the development gap (11, E) has a width, in relation to the magnetic bars (N2) acting in this region, which extends over the width of the uniform magnetic field of the magnetic bars, excluding the non-uniform magnetic field (R). The mixture carpet (23) is guided as desired by matching the lengths of the magnetic bars (N, S) and/or by mechanical guiding or limiting elements (25, 28).
