摘要 |
A developing device for an electrophotographic apparatus includes a developing magnet roller, a transfer magnet roller and a separator for separating these rollers. Each of these rollers has a sleeve which is rotatably fitted around a columnar magnet piece. Between the sleeve of the developing magnet roller and the separator is a gap which is greater than the thickness of a developer layer formed on a surface of the sleeve of the developing magnet roller.
