摘要：
The present disclosure relates to an electrophotographic method of obtaining a lithographic printing plate comprising the step of transferring a toner image from a toner image bearing member to a toner receiving plate, said toner receiving plate comprising a thermoplastic film support and a crosslinked hydrophilic layer thereon, characterized in that said crosslinked hydrophilic layer either carries on top thereof or incorporates spacing particles forming protuberances on said layer.According to a preferred embodiment, the average particle diameter by volume of the spacing particles is at least twice the average particle diameter by volume of the electrophotographic toner.
