An ink jet cartridge comprises an ink jet head unit for discharging the ink, and an ink tank unit having an ink supply port for supplying the ink to the ink jet head unit. The ink tank unit has a partition portion for partitioning between an ink storing portion for storing the ink to be supplied to the ink jet head unit and a negative pressure generating member receiving portion having a negative pressure generating member. The ink supply port is provided on the negative pressure generating member receiving portion. The partition portion has an ink communicating portion at an end portion of the partitioning portion on the side of the negative pressure generating member receiving portion where the ink supply port is provided, and makes contiguous the ink storing portion and the negative pressure generating member receiving portion in a movement direction of the ink tank unit when discharging the ink.

An ink leaking from an atmosphere communication hole of a waste ink container is guided to an end portion of the waste ink container. Electrodes are provided for shutting off an ink guide path. By this, the ink leaking through the atmosphere communication hole is inherently guided into the end portion of the container to come into contact with both of the electrodes. By contacting of the ink, a resistance value between the electrodes is varied to permit detection of ink leakage based on the variation of the resistance value. As a result, ink leakage from a waste ink container employed in an ink-jet printer or so forth can be certainly detected. Also, sealing ability of the waste ink container can be enhanced.

In a liquid jet apparatus with ink discharging orifices and a recording apparatus using the same, each of the orifices has a trapezoidal cross-section, with at least the opposite bottom corners thereof having curved portions. The orifices preferably have a shape convergently tapering toward the outside of the recording head. The orifices are durable against temperature changes, impact, etc., which tend to cause cracking.

An image forming system comprises an image forming apparatus and an external terminal. The image forming apparatus has a receiving part for receiving operation input information on an operation input into an operation screen from the external terminal, a specifying part for specifying a first program to which an execution instruction is given through the operation screen on the basis of the operation input information, a determination part for determining a second program having the same function as that of the first program as an execution object program on the condition that the second program is installed in the external terminal, and a notification part for notifying the external terminal that the second program is determined as the execution object program. The external terminal executes a processing in accordance with the second program and displays a result of the processing executed in accordance with the second program.
