Photosensitive material processing apparatus
A liquid drop, which remains at a trailing end portion of a base surface side of a sheet which has passed through a roller pair, is removed by a first liquid drop removing roller which contacts only the base surface side. A spreading roller, which spreads moisture which has moved to a surface of the first liquid drop removing roller, is pressed to tightly contact the first liquid drop removing roller. A second liquid drop removing roller contacts only an emulsion surface of the sheet, and removes a liquid drop adhering to the emulsion surface. A spreading roller is pressed to tightly contact a surface of the second liquid drop removing roller as well, and spreads moisture at the surface thereof.
