Lithographic printing plate precursor, method for preparing lithographic printing plate, and lithographic printing method

A lithographic printing plate precursor, comprising:

• a support;
• and
• an image-recording layer on the support,
• wherein the image-recording layer contains an infrared absorber, a polymer A that has a weight-average molecular weight of more than 15,000 and 150,000 or less, and a polymerizable compound B that has a weight-average molecular weight of 1,000 or more and 15,000 or less,
• the polymer A is a polymer represented by Formula (I),
• AP-(BP)nP Formula (I)
• in Formula (I), AP represents an nP-valent organic group having a hydrogen bonding group, BP represents a group having 2 or more polymerizable groups, nP represents an integer of 2 or more, and weight-average molecular weight of AP/(molecular weight of BP×nP) is 1 or less, and
• the nP-valent organic group represented by AP includes a structure represented by any of Formula (A-1) to Formula (A-3),
• in Formula (A-1), RA1 represents a hydrogen atom or an alkyl group having 1 to 8 carbon atoms, and the portion of a wavy line represents a bonding position with other structures.
