ABSTRACT:
A development assisting apparatus is provided which can give a finish of uniform quality and in a short time, irrespective of changes in temperature due to regional temperature differences or changes with the seasons. A case side clamping face 6 is provided on a front face of a case body 2, and an openable lid 3 with a lid side clamping face 16 provided on an inner face thereof, is hinged so as to be openable relative to the case side clamping face 6. A heating device 7 is provided on the case body 2, and in this case the case side clamping face 6 rather than the lid side clamping face 16 is heated so that an instant camera film 1 pressed and held between the clamping faces 6, 16 is kept warm. Due to the film 1 being kept warm by the heating and heat retention, then uniform development without irregularities is possible.
