Abstract:
1. An image recorder applying a laser beam to an image recording material thereby recording a two-dimensional image on said image recording material, comprising: a recording drum having an outer peripheral surface to which said image recording material is fixed; a rotation element rotating said recording drum; a recording head having a laser beam source emitting a laser beam and an objective lens applying said laser beam to said image recording material fixed to the outer peripheral surface of said recording drum; a recording head moving element moving said recording head in a subscanning direction parallel to the rotational axis of said recording drum; a gas injection element diffusing gas generated from said image recording material irradiated with said laser beam by injecting prescribed gas in the vicinity of said objective lens, said gas injection element moving in said subscanning direction along with said recording head; a first suction element located downstream beyond said gas injection element in relation to the rotational direction of said recording drum for sucking said gas diffused by said gas injection element, said first suction element moving in said subscanning direction along with said recording head; and a second suction element located downstream beyond said first suction element in relation to the rotational direction of said recording drum for sucking said gas diffused by said gas injection element from a continuous opening over the total width of an image recording area of said image recording material in said subscanning direction.
