Structure for mounting development cartridge in image forming apparatus

An image forming apparatus comprising:

• a main body comprising an opening, a door to open and close the opening, and an accommodation portion;
• a development cartridge comprising a driving end and a non-driving end;
• a tray on which to mount a development cartridge, the tray being movable between a mounting position and a withdrawal position through the opening;
• an elevating guide member to be elevated to a first position at which the tray is supported to slide between the mounting position and the withdrawal position, and a second position at which the development cartridge is accommodated in the accommodation portion, in conjunction with an opening and closing operation of the door;
• a non-elastic support member to non-elastically support the driving end of the development cartridge with respect to the tray;
• and
• an elastic support member to prevent the development cartridge from being displaced due to an impact applied to the tray when the tray slides into the mounting position, wherein the elastic support member is elastically deformed in a detachment direction and an elevating direction to absorb the impact.

An image forming apparatus comprising:

• a main body comprising an opening and an accommodation portion;
• a development cartridge detachable from the main body;
• a tray on which to mount the development cartridge, the tray being movable between a mounting position inserted into the main body through the opening, a withdrawal position extracted from the main body, and an accommodation position at which the development cartridge is accommodated in the accommodation portion;
• and
• an elastic support member to prevent the development cartridge from being displaced due to an impact applied to the tray when the tray slides into the mounting position, wherein the elastic support member is elastically deformed in a detachment direction and an elevating direction to absorb the impact.
