Step S2-16
When printing is started, the detection unit 15 starts actual measurement of the transfer voltage and the transfer current. The transfer condition setting unit 12 compares the actual value of the transfer information obtained from the detection unit 15 with the lower limit of the limit transfer information. If the actual value is larger than the lower limit of the limit transfer information, the process proceeds to step S2-17. If it is smaller, the process proceeds to step S2-19.
Step S1-17
The transfer condition setting unit 12 compares the actual value of the transfer information obtained from the detection unit 15 with the upper limit of the limit transfer information. If the actual value is smaller than the upper limit of the limit transfer information, the process proceeds to step S2-18. If it is larger, the process proceeds to step S2-20.
