INK CARTRIDGE AND IMAGE FORMING APPARATUS |
摘要 |
An image forming apparatus includes an image forming device to form an image and an ink cartridge that includes a deformable ink supply bag having an ink supply port; a deformable waste ink collection bag having a fluid gateway; and a cartridge housing to accommodate the deformable ink supply bag and the deformable waste ink collection bag at the same time. A connecting member having a non-return valve is provided to connect the deformable ink supply bag and the deformable waste ink collection bag with each other at a section other than the ink supply port and the fluid gateway. The non-return valve prevents ink from flowing from the waste ink collection bag into the ink supply bag. A non-return valve control mechanism is provided not to operate the non-return valve in an initial state in which the ink supply bag is initially filled with ink. |
