PROBLEM TO BE SOLVED: To achieve good refill characteristics of ink corresponding to increase in viscosity of the ink under a low temperature environment in an inkjet recorder that performs delivering of ink by a divisional heat pulse and controlling of temperature along with the delivering. SOLUTION: In a case where controlling of temperature by a table No. 1 is performed under a low temperature environment when using ink having a high viscosity, blurring may occur in high-duty recording caused by defective refilling. As for a table No. 2 or a table No. 3, defective refilling also occurs so that blurring recording occurs. However, in a case of controlling of temperature by a table No. 4, a pulse width of a preheat pulse is made smaller than that for table No. 1 in the heretofore controlling of temperature even in the same low temperature environment. Consequently, blurring is eliminated in high duty recording without being caused by defective refilling. COPYRIGHT: (C)2009,JPO&INPIT
