Patent ID: 7857412

Claim:
An inkjet recording apparatus which records an image on a recording medium by discharging ink from a plurality of head chips disposed in a recording head, each head chip having multiple nozzles and thermal-energy-generating unit configured to discharge ink through the nozzles by thermal energy, the apparatus comprising: a temperature-detecting unit configured to detect the temperature of each of the head chips disposed in the recording head; and an adjusting unit configured to adjust the discharge of ink from only band-boundary nozzles corresponding to a boundary region between two adjacent head chips for each of the head chips on the basis of the temperature detected by the temperature-detecting unit, wherein, when a temperature difference between the adjacent two chips exceeds a predetermined threshold, the adjusting unit adjusts the band-boundary nozzles of each of the two adjacent head chips in a boundary region between the two adjacent head chips such that a usage rate of a chip having a higher temperature is lower than a usage rate of a chip having a lower temperature.
