1. A method for producing a lithographic printing plate precursor,sequentially carrying out the steps a and b or sequentially carrying out the steps b and a and then carrying out the step c on a hydrophilic aluminum support,the step a is an image recording layer forming step of forming an image recording layer,the step b is a coating step of coating a coating liquid containing a hydrophilizing agent so as to overlap a partial region of the image recording layer formed in the step a,the step c is a cutting step of cutting the lithographic printing plate precursor so that the region coated with the coating liquid is within 1cm of the end of the cut lithographic printing plate precursor,in the step c, the dicing is performed so that the amount of sagging at the end portion becomes 30 to 150 μ
