Abstract
In a photosensitive material processing apparatus having a wash tank for washing photosensitive material with a relatively large volume of water after development, means for releasing silver cations into wash water is provided for preventing bio-slime generation in the wash tank. Silver cations can be dissolved out from a silver alloy through electrolysis or from a silver release agent. A method for preventing bio-slime from accumulating in the wash tank includes the steps of: releasing silver cations into wash water, and optionally, draining wash water from the wash tank, and forcedly drying the wash tank.
