An image recording apparatus of the present invention comprises an inkjet head which includes a nozzle plate where a plurality of nozzles that shoot ink are arranged in a column and an ink chamber which retains ink and is connected to the plurality of nozzles, at least one maintenance suction section which has a suction area larger than the nozzles, a suction section driving mechanism which causes the suction area to face the nozzles and moves the suction section relatively in the nozzle arrangement direction, and a positive pressure applying section which applies a positive pressure to the ink chamber. The maintenance suction section sucks in ink near the nozzles as moving in the nozzle arrangement direction, while the positive pressure is being applied to the ink chamber.

An ink jet printer includes ink jet heads for recording an image on a recording medium, an ink bottle for holding ink, an ink supply path connecting the ink bottle to each ink jet head, and an electromagnetic valve provided on the path. In the printer, the bottle, the valve and the heads are arranged downward in this order in the vertical direction, the path constantly exists upwards in the vertical direction in such a manner that air entered into the path moves up above the valve due to a difference in the specific gravity between the air and the ink, the path is provided with a branching portion provided between the valve and the heads, and a sub ink tank is provided at an end of the branching portion so as to be positioned lower than the heads in the vertical direction.

An ink jet head includes four plate-like piezoelectric bodies each having a primary surface having a plurality of parallel grooves formed therein in a predetermined direction, a end surface on which a one end of the groove is open, and an electrode formed on the inner surface of the groove. These piezoelectric bodies are stacked one upon the other on the primary surfaces under the state that the openings of these piezoelectric bodies are allowed to face the same direction, and that the primary surfaces of these piezoelectric bodies are allowed to face the same direction. Further, formed is a common liquid supply path allowing the plural grooves of the piezoelectric bodies to communicate with each other to form ink flow path.

Provided is a system for determining a number of particles, which has a simplified and compact structure as well as a reduced cost. The system comprises a diluter (PND2) arranged at a connecting point of a main flow channel (ML) and a dilution gas flow channel (DL), a dilution gas flow rate control part (MFC3) that controls the flow rate of the dilution gas introduced into the diluter (PND2), a particle number measuring unit (2) that measures a number of solid particles in a diluted exhaust gas, a bypass flow channel (BL3) that bifurcates from between the diluter (PND2) and the particle number measuring unit (2) in the main flow channel (ML) and in which a constant flow rate unit (CFO3) is arranged, a suction pump (P) that is connected downstream of a converged point of the main flow channel (ML) and the bypass flow channel (BL3), and an information processing unit (4) that calculates the dilution factor of the exhaust gas based on a dilution gas flow rate (Q1) controlled by the dilution gas flow rate control part (MFC3), and a total of a unit flow rate (Q2) of the particle number measuring unit (2) and a set flow rate (Q3) of the constant flow rate unit (CFO3).

A transfer unit includes a pair of guide and field stabilizer members disposed adjacent to a transfer member and along a conveying path for a transfer sheet. A voltage is applied to the stabilizer members which is of the same polarity as a bias voltage applied to the transfer member. It is assured that transfer sheet reliably contacts the pair of field stabilizer members as it passes therebetween.
