In order to provide an image forming apparatus capable of forming a quality image
by restricting a distance between a developing roll and a magnetic roll with a
simple structure, an image forming apparatus comprises a magnetic roll 1 and
a developing roll 2 that are disposed in parallel with a predetermined distance
and a developing unit 50 that develops an electrostatic latent image on
a photosensitive body drum 3 disposed on the image forming apparatus main
body using a toner thin layer formed on the surface of the developing roll by the
magnetic roll, wherein a member for holding rotational axes having a pair of openings
for holding, which fits and holds rotatably and integrally each of rotational axes
of the magnetic roll and the developing roll is provided, the opening for holding
of the developing roll being capable of swinging around the axis center of the
opening for holding of the magnetic roll.
