A signal detecting system for reading a charge signal from an image recording medium includes a signal storing circuit, a first low-pass filter into which the charge signals stored in the signal storing circuit are input, a first sample hold circuit which sample-holds the charge signal passing through the first low-pass filter, a second low-pass filter into which the charge signals stored in the signal storing circuit are input, a second sample hold circuit which sample-holds a reference level signal when the input of the charge signal passing through the second low-pass filter is at a reference potential, a difference circuit which outputs as an image signal the difference between the charge signal and the reference level signal, and a controller which controls the initiating timings of the sample hold circuits so that the initiating timing of the first sample hold circuit is earlier than that of the other.
