Customer replacement unit memory contact unit pressured according to movement of tray in an image forming apparatus

An image forming apparatus, comprising:

• a main body;
• a tray, slidably coupled to the main body, to receive a toner cartridge;
• and
• an interlocking unit to apply a force to a customer replacement unit memory (CRUM) contact unit when the tray is pushed into the main body to thereby cause the CRUM contact unit to descend and be electrically coupled to the toner cartridge, and to release the force applied to the CRUM contact unit when the tray is pulled out from the main body such that the CRUM contact unit is electrically decoupled from the toner cartridge.

An image forming apparatus, comprising:

• a main body;
• a tray, slidably coupled to the main body, to receive a toner cartridge;
• and
• an interlocking unit, including:
• a lever, coupled to the tray, to rotate in a first direction when the tray is pushed into the main body and to rotate in a second direction when the tray is pulled out from the main body, and
• a link member, coupled to the lever, to move when the lever is rotated in the first direction such that a customer replacement unit memory (CRUM) contact unit is lowered to be electrically coupled to the toner cartridge, and to move when the lever is rotated in the second direction such that the CRUM contact unit is raised by an elastic force to release the electrical coupling to the toner cartridge.
