PURPOSE:To perform stable treatment of a photosensitive material for a long time in an automatic treating apparatus by constituting the part of the automatic treating apparatus so as to be in contact with a treating chemical of a specified rubber member. CONSTITUTION:A rubber member contg. <=20wt.% plasticizer and having <=75 hardness is used as a material being in contact with a treating chemical of an automatic treating apparatus. Natural rubber, synthetic rubber, or styrene/ butadiene rubber, etc., is used for such material. The hardness, elasticity, strength, etc., are adjusted by adding a plasticizer, filler, etc., to the crude rubber. A phthalic ester type, aliphatic dibasic acid type, phosphoric ester type plasticizer may be used suitably. Thus, stable treatment of a photosensitive material in an automatic treating apparatus has become possible for a long time. |
