In an ink jet recording device of the type wherein ink droplets are ejected from orifices using thermal energy and the heater for supplying the thermal energy is oriented in a direction substantially perpendicular to the orifice surface, a cleaning unit is provided for cleaning the head of the device. The cleaning unit includes an integral wiper and ink pool. In cleaning the head, ink that gathers on the wiper will drip downward by its own weight, resulting in very little spread toward adjacent orifice, thereby minimizing the degree at which different color inks mix on the surface of the head.
