Developing cartridge having a detachable structure with respect to a body of an image forming apparatus, and an image forming apparatus having the same

An image forming apparatus comprising:

• a body;
• a cover which is configured to open/close one side of the body;
• a tray which is installed to the body through the one side open by the cover as to enable a sliding motion;
• at least one developing cartridge which is installed at an inside of the body while accommodated at the tray and which is provided at one side thereof with an interface terminal to be supplied with a power used to form an image;
• a power supply unit which is configured to supply a power to the at least one developing cartridge installed at the body;
• and
• a connection terminal which is connected to the power supply unit and is configured to make contact or to separate from the interface terminal in linkage with the cover,
• wherein when the cover opens the body, the connection terminal is separated from the interface terminal of the at least one developing cartridge to prevent the connection terminal from interfering with the at least one developing cartridge installed at the tray in a process of moving the tray.

An image forming apparatus comprising:

• a body;
• a cover which is configured to open/close one side of the body;
• a tray which is installed to the body through the one side open by the cover as to enable a sliding motion;
• at least one developing cartridge which is installed at an inside of the body while accommodated at the tray and is provided at one side thereof with an interface terminal to be supplied with a power used to form an image;
• and
• a connection terminal which is configured to move in linkage with an open/close motion of the cover such that the connection terminal makes contact with the interface terminal when the cover closes the body and is separated front the interface terminal when the cover opens the body.

An image forming apparatus comprising:

• a cover which is configured to open/close one side of a body;
• at least one developing cartridge which is installed at an inside of the body while accommodated at a tray and is provided at one side thereof with an interface terminal to be supplied with a power used to form an image;
• a connection terminal plate which is configured to slidably move in a second direction different from a first direction in linkage with an open/close motion of the cover;
• and
• a guide rail which is movably coupled to one side of the body and moves in linkage with the cover while connected to the cover, wherein the connection terminal plate presses a connection terminal or releases a pressing force on the connection terminal pressing while moving in linkage with the guide rail,
• wherein the guide rail is slidable in a back and forth direction and the connection terminal plate is slidable in a back and forth direction different than the directional movement of the guide rail.
