Ink jet recording head and ink jet recording apparatus provided with the recording head

An ink jet recording apparatus for performing recording by discharging ink for a recording head, wherein

• said ink jet recording apparatus comprises:
• a cleaning member which moves, relative to the ink jet recording head, into contact with a surface provided with an ink discharge port and having an area provided with said ink discharge port for discharging ink and which serves to clean said area;
• and
• a supporting member for mounting therein the recording head, said recording head comprising a recessed portion provided at said area and in a vicinity of said ink discharge port, said recessed portion being positioned in a route of said cleaning member moving in contact with said ink discharge port and upstream of said ink discharge port with respect to a moving direction of said cleaning member as it moves relative to the ink jet head and relative to the surface on which the ink discharge port is formed.
