Abstract:
1. An image forming apparatus comprising: a magnetic roll and a developing roll disposed in parallel at a predetermined distance; a developing unit for developing an electrostatic latent image on a photosensitive body drum disposed on a main body of said image forming apparatus using a toner thin layer formed on the surface of said developing roll by means of said magnetic roll; a supporting member having a pair of openings for rotatably holding a rotational axis of said magnetic roll and a rotational axis of said developing roll wherein said opening for holding said rotational axis of said developing roll is capable of pivoting about an axis center of said opening for holding said rotational axis of said magnetic roll; and a protrusion and a spring located between said developing roll and said magnetic roll axes for pivoting said opening of said supporting member for holding said rotational axis of said developing roll about said axis center of said opening for holding said rotational axis of said magnetic roll.
