Zusammenfassung:	PURPOSE:To provide a developing temperature compensator for instant camera eliminating the futile use of film and having excellent operability. CONSTITUTION:A temperature measuring circuit 21a detects the surface temp. of a spread roller 12. that is, the developing temp. of instant film and in an AEIC 40 as a circuit for comparing temp. and correcting exposure, a reference temp. set in advance is compared with the developing temp. and a heater 21 is controlled to attain exposure corrections for overexposure with respect to a proper exposure when the developing temp. is lower than the reference temp. and for underexposure with respect to the proper exposure when the developing temp. is higher than the reference temp., based on the result of the comparison.
