Structure for electric contact portion of toner cartridge

A toner cartridge comprising:

• a body having a toner outlet therein;
• a rotation member provided on the body for receiving rotational drive from a driving member of an image forming apparatus;
• and
• an electric contact portion for electrical connection with the image forming apparatus, wherein, based on a force applied to the body by an external member referred to as a first force and a force applied to the body by rotation of the rotation member referred to as a second force, a contact surface of the electric contact portion faces between a direction of the first force and a direction of the second force.

An image forming apparatus comprising:

• a developing device to supply toner to an electrostatic latent image formed on a photoconductive body;
• a driving member configured to transmit rotation;
• a second electric contact portion;
• and a detachable toner cartridge comprising:
• a fixing portion having a toner outlet formed therein, a toner storing portion rotatably connected to the fixing portion, the toner storing portion comprising a rotation member engaged with the driving member to receive rotational drive, the toner storing portion to transport toner to the fixing portion,
• an electric contact portion provided in the fixing portion to electrically connect to the second electric contact portion, wherein, based on a force applied to the fixing portion by an external member referred to as a first force and a force applied to the fixing portion by rotation of the rotation member referred to as a second force, a contact surface of the electric contact portion faces between a direction of the first force and a direction of the second force.
