Abstract

PURPOSE: To let always stable visible images be obtained by so constituting the device that a magnetic blade may be readily set to a developer supporting means by maintaining the specified spacing and may be held without having any effect of the temperature change of environment.
CONSTITUTION: A position setting member 2 is provided to permit easy setting of the spacing between a developer supporting means 1 and a magnetic blade 4 at the specified value. This position setting member 2 has the function as a bearing member of a developing roller 6. In addition, a spacing setting member 3 is provided on the same axis as the axis 1a of the developer supporting means 1 in order to set the spacing between the developer supporting means 1 and latent image supporting means 12 at the specified value. Next, the change in the spacing between the developer supporting means 1 and magnetic blade 4 owing to temperature change is determined by the thermal expansion of the developer supporting means 1 and the thermal expansion from the bearing hole of the position setting member 2 up to the end position of the magnetic blade 4, with less influence of thermal expansion on account of their constitution. In this way, always stable visible images are obtainable.
