Abstract

Abstract There is provided a liquid jet recording apparatus using recording liquids having viscosities depending upon an ambient temperature. This apparatus comprises: at least one liquid droplet jet head for emitting at least one recording liquid droplet each time the head is driven; drive means for repeatedly driving this head; and control means for controlling the frequency of the repetitive driving of the head by the driving means in accordance with the ambient temperature.
