機構。[Claims for Utility Model Registration] 1. In an image processing apparatus using a recording drum and a magnetic brush developing device equipped with a developing roll, the developing roll is moved relative to the recording drum by rotation of an eccentric cam made of an elastic body. The developing roll is moved toward and away from the recording drum, and is moved away from the recording drum when the recording drum rotates at high speed and approaches when the recording drum rotates at low speed, and when the developing roll approaches the recording drum, the amount of approach is reduced by a stopper. A position changing mechanism for a magnetic brush developing device, characterized in that the distance between the developing drum and the recording drum is maintained constant. 2. A position changing mechanism for a magnetic brush developing device according to claim 1, wherein the eccentric cam has a main body made of an elastic body and a peripheral part made of a rigid body.
