摘要:
A manufacturing method of a lithographic printing plate, which comprises: imagewise exposing a lithographic printing plate precursor comprising a support and an image-recording layer; and removing a non-image area of the image-recording layer in a development processing tank that has a reservoir of a first aqueous solution having pH of from 2 to 10 by rubbing the non-image area with at least one rubbing member in a state of being immersed in the reservoir of the first aqueous solution, wherein the removal of the non-image area with the at least one rubbing member is carried out after an elapse of 2 seconds or more from an immersion in the reservoir of the first aqueous solution.
