ABSTRACT:
In a noise rejecting compensation circuit for developing apparatus to be replenished with developing liquid during a time when the integral value derived from summing up an electric signal through integrator means by predetermined periods reaches a predetermined value from another value, said electric signal is transformed through photocell means from a light emitted from light source means and interfered with film means, differential amplifier means is provided at the input side of said integrator means, leakage by-pass having condenser means is connected with said differential amplifier means in parallel, and leakage contact means is provided to be closed at a time when said light source means is turned off in said leakage by-pass means.
