Claim 7:
8. A treatment method comprising:
a developing step of performing development by removing a non-exposed portion of a flexographic printing plate precursor after imagewise exposure using a developer containing a washing solution; and
a rinsing step of supplying a rinsing liquid containing substantially only water as a component to at least a surface of the flexographic printing plate precursor after development, from which the non-exposed portion of the flexographic printing plate precursor has been removed,
wherein the developer which is used for the development is fed to a developer storage tank which stores the developer via a first liquid feeding path,
the rinsing liquid supplied in the rinsing step is fed to the developer storage tank via a second liquid feeding path different from the first liquid feeding path, and
in the developing step, the developer stored in the developer storage tank is repeatedly used for the development.
