Abstract
A coloring apparatusincludes a coloring nozzlefor spouting a coloring material, a signal generator, and a controller. The coloring nozzleincludes an electromagnetic valve. The signal generatoroutputs signals for spouting the coloring material from the coloring nozzleto both a CPUof the controllerand a driving circuit. The CPUoutputs a signal for keeping the electromagnetic valveopen to the driving circuitwhen a frequency of the signals from the signal generatoris higher than a specific frequency. When at least one of the signals from the CPUand the signal generatoris inputted, the driving circuitapplies a spike voltage A and then applies a hold voltage B to a coil. While at least one of the signals from the CPUand the signal generatoris inputted, the driving circuitapplies a spike voltage A and then continuously applies a hold voltage B to a coil
