Abstract: PURPOSE:To obtain always a sharp image by examining a developer using ultrasonic waves, regulating concn. of the developer, and replenishing the fresh developer in accordance with the measured concn. CONSTITUTION:An ultrasonic concn. detector 32 having an ultrasonic wave oscillator 30 and an ultrasonic wave receiver 31 facing each other is arranged in the inside of a developing device 9.
