Zusammenfassung:A solid-concentration measuring apparatus includes an ultrasonic transmitter, an ultrasonic receiver, and a response-time integrator. The ultrasonic transmitter transmits a single-pulse ultrasonic wave to a liquid toner. The ultrasonic receiver receives the single-pulse ultrasonic wave. The ultrasonic transmitter transmits again a single-pulse ultrasonic wave after a predetermined time has passed from when the ultrasonic receiver receives the single-pulse ultrasonic wave. The response-time integrator measures a response time from transmission to reception of each single-pulse ultrasonic wave, and integrates the response time with respect to each set of N pulses (N>1). A solid concentration of the liquid toner is calculated based on the integrated response time.
