Image forming apparatus

An image forming apparatus, comprising:

• an apparatus body;
• an image bearing member;
• a developing unit comprising a developing container configured to store developer, a developer bearing member configured to rotate while bearing the developer stored in the developing container, and a developing magnet provided within the developer bearing member and comprising a plurality of magnetic poles in a circumferential direction, the developing unit being removably provided to the apparatus body and configured to develop an electrostatic image formed on the image bearing member;
• a power supply configured to apply a developing bias to the developer bearing member;
• and
• a contact portion electrically connected with the power supply,
• wherein the developing unit comprises a conductive member which is made of a conductive resin comprising a fixing portion fixing the developing magnet so that the magnetic poles of the developing magnet is fixed unrotatably with respect to the developing container, the conductive member being provided to electrically connect the contact portion with the developer bearing member.
