Abstract

PURPOSE:To maintain solution temperature readily at the specified temperature by dipping the one which comprises packing and sealing material of about 20 deg.C in melting point in a case made of sheets of good head conductivity and freezing this, in a photographic processing solution. CONSTITUTION:Material 4 of about 20 deg. in melting point such as acetophenone (melting point 19.5-20.5 deg.C) is packed and sealed in a case 3 made of sheet of good heat conductivity such as aluminum foil. The one comprising freezing this is put in the developing solution 2 or the like in a vat 1 in order to maintain the constant temperature of the photographic processing solution, whereby the constant temperature may be maintained for a long time with ease without requiring any thermostatic device or the like.
