PURPOSE:To permit a uniform and stable developing process with a smaller amt. of a developing soln. by supplying the unused developing soln. onto a photosensitive planographic printing plate (PS plate) from a slit, conveying the plate upward by using an inclining roller and passing the plate further through a developing tank by using a guide roller. CONSTITUTION:The substantially unused developing soln. is supplied from a slit constituted of two sheets of plate materials at the bottom end of a developing soln. supplying member 7 onto the PS plate 2 in the case of automatically conveying the PS plate 2 and subjecting the same to the developing process. The PS plate is conveyed upward by using the inclining roller 4 and is further passed through the developing tank 11 by using the guide roller 12. The slit formed of two sheets of the plate materials of the developing soln. supplying member 7 is preferably so constructed as to be adjusted to the slit spacing corresponding to the outflow rate of the developing soln. from the developing soln. supplying member 6. The uniformity in development is thereby improved and the developability particularly at the front end part and both side parts is improved in a method for develop the PS plate with a small amt. of the developing soln. |
