Method for forming images

A method for forming images comprising the steps of imagewise exposing a photopolymerizable image-forming material comprising a substrate provided thereon with an image-recording layer which comprises a photopolymerization initiator system sensitive to light rays whose wavelength falls within the visible to ultraviolet ranges, a polymerizable compound carrying at least one ethylenically unsaturated group and a binder polymer and then developing the imagewise exposed image-forming material with a developer containing at least one carbonate and at least one hydrogen carbonate, containing at least one surfactant selected from the group consisting of anionic surfactants and nonionic aromatic ether type surfactants represented by the following general formula (1) in an amount ranging from 1.0 to 10% by weight on the basis of the total weight of the developer, and having a pH value ranging from 8.5 to 11.5 and an electrical conductivity x falling within a predetermined range:

• 30<x<100mS/cm:
• X—Y—O-(A)n-(B)m—H (1)
• wherein, X represents a substituted or unsubstituted aromatic group, Y represents a single bond or an alkylene group having 1 to 10 carbon atoms, A and B may be the same or different from one another and represent either —CH2CH2O— or —CH2CH(CH3)O—, and each of n and m represents 0 or an integer ranging from 1 to 100, provided that n and m do not simultaneously represent 0 and that if either n or m represents 0, n and m are not 1.
