A developer composition for developing a lithographicnprinting plate having a negative recording layer on which annimage is recorded via an infrared laser, the compositionncontaining a nonionic surfactant, and a process for formingnan image on a lithographic printing plate. The processncomprises the steps of imagewise exposing a lithographicnprinting plate having a negative recording layer on which annimage is recorded via an infrared ray and which contains anninfrared ray absorbent, a radical generator and a radicallynpolymerizable compound, and then developing the lithographicnprinting plate with the developer composition containing annonionic surfactant. |
