望の位置に設けることができる。FIG. 1 shows a structural example of a main part of the ink jet recording apparatus of the present invention. In this example, the energy range of the recording signal is switched in n steps according to the temperature. In the figure, SA is a density signal, which corresponds to the desired ink amount at the time of printing by halftone expression, and this signal is supplied to the limiters 1-1 to 1-n. On the other hand, the environmental temperature C is converted into an electric signal SD by the temperature detection unit 5 including a temperature sensor,
This signal SD is guided to the switch 6. Here, the temperature sensor is, for example, in the vicinity of the nozzle portion of the head 4, an ink supply pipe,
Alternatively, it can be provided at a desired position such as an ink tank where the environmental temperature can be appropriately detected.

れる。The switching device 6 outputs a switching signal SE according to the temperature information, and selects a limiter suitable for the temperature state at that time.
Therefore, the density signal SA input to the limiter is added as a recording signal SB to the inkjet head 4 with a characteristic suitable for the temperature of the inkjet head 4 at that time.

することができる。Here, the limiters 1-1 to 1-n limit the energy (driving output amount) of the recording signal within the range that does not exceed the stability limit at the corresponding temperature with respect to the temperature characteristic of stable discharge in FIG. When a signal SA that exceeds the limit is input, a signal near the limit value
It outputs SB. As a result, the head 4 can operate stably even if an excessively large or too small recording signal is input depending on the density at that time. The limiters 1-1 to 1-n may be in various forms such as switches and arithmetic means. The inputs and outputs of the limiters 1-1 to 1-n can have the relationship shown in FIG. 2, for example.

とが可能となる。As described above, the recording means having the ink jet head is such that the operating state, that is, the stable ejection range changes depending on the temperature,
By keeping the energy of the recording signal within the stable ejection range according to the detected temperature, stable ejection can always be performed.

タに対して制限を付すことで同様な効果が得られる。Here, as a method of adjusting the energy of the recording signal applied to the recording means, in an inkjet recording apparatus that controls the ejection amount by making the voltage of the recording signal supplied to the inkjet head variable, a limitation is imposed on the voltage data. good. Further, in the ink jet recording apparatus in which the ejection amount is controlled by the width (pulse width) of the recording signal, the same effect can be obtained by limiting the pulse width data.

However, a limiter having a switchable element for setting a limit level is provided and only that element is switched. However, the same effect can be obtained.

それを防止できることになる。FIG. 3 shows an inkjet recording apparatus in which a latch circuit 7 is added to the apparatus shown in FIG. According to this example, the temperature switching signal SE is held only during printing by the printing start signal SF, and the limiter 1-1 is held during printing.
It can prevent ~ 1-n from switching. That is, for example, when the number of switching steps is reduced, the density unevenness of the recorded image may occur if the switching occurs during printing, which can be prevented according to the present example.
