Abstract: Provided are a processing method and a processing apparatus in which a concentration of a solid content of a development fatigue liquid is low and a moisture content of a discharged solid substance is small. The processing method is a method for removing a first solid substance having a smaller specific gravity than the washout liquid and a second solid substance having a larger specific gravity than the washout liquid from a development fatigue liquid including a solid substance generated by removal of a non-exposed portion of a photosensitive resin plate that has been exposed in an image shape by development using the washout liquid. The method includes a first step of centrifugally separating the first solid substance and the second solid substance included in the development fatigue liquid in a rotating container, accumulating the second solid substance on an inner wall of the container, and accumulating the first solid substance on a holding member provided in the container, a second step of discharging the development fatigue liquid from the container in a state in which the first solid substance accumulated on the holding member is held on the holding member, and a third step of rotating the container, thereby removing the first solid substance held on the holding member from the holding member.

Abstract: Provided are a treatment device and a treatment method capable of easily reusing a used rinsing liquid, and reducing the amount of waste liquid. A treatment device has: a developing portion which is provided with a developing unit which performs development by removing a non-exposed portion of a flexographic printing plate precursor after imagewise exposure using a developer containing a washing solution; a rinsing portion which is provided with a rinsing liquid supply portion which supplies 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; a developer storage portion which has a developer storage tank which stores the developer which is used for the development in the developing portion; a first liquid feeding path through which the developer after development is fed to the developer storage tank of the developer storage portion; and a second liquid feeding path different from the first liquid feeding path, through which the rinsing liquid supplied by the rinsing portion is fed to the developer storage tank of the developer storage portion, and the developing portion repeatedly uses the developer stored in the developer storage tank of the developer storage portion to perform the development.

Abstract: Provided is a conveying type washing device capable of achieving both maintainability and productivity. This conveying type washing device develops a flexographic printing plate precursor after imagewise exposure using a washing solution. The conveying type washing device has a conveying unit that conveys the flexographic printing plate precursor through a conveying path including a curved conveying path, and a development unit that develops the flexographic printing plate precursor in a state in which the flexographic printing plate precursor is immersed in the washing solution by the conveying unit and conveyed.
