Abstract
A photosensitive material drying method for drying a photosensitive material conveyed along a conveying path, including steps of: training a front surface and a rear surface of the photosensitive material alternately around a plurality of heat rollers whose outer circumferences are heated by heat sources; heating the photosensitive material by an amount of heat provided on a basis of a temperature of the outer circumferences of the heat rollers and on the basis of a time of contact between the photosensitive material and the heat rollers; and evaporating moisture from a surface of the photosensitive material not contacting the heat rollers. High-quality drying can be effected in a small space and with little use of electric power. Efficient drying in which dimensions of films are stable can be carried out.
