Abstract
An electrolytic apparatus, for supporting a lithographic printing plate, including a guide roller for transporting an aluminum web. The guide roller includes a skeleton section formed with a strong material, a liquid contact section on the surface of the skeleton section, and a nonwoven fabric is provided on the liquid contact section and contacts a surface of an aluminum web. The liquid contact section is formed with a fluororesin coating of 100-3000 &mgr;m in thickness, and the insulation resistance value of the fluororesin coating is 10 &OHgr;cm or more in volume resistivity. The nonwoven fabric is formed mainly with polyphenylene sulfite or fluororesin of 5-50 mm in thickness. Additionally, the nonwoven fabric is condensed in the direction of the guide roller axis, and is treated with a surface finish so as to have a surface hardness in the range of 50-95.
