There is provided an imaging device which eliminates complexity in reading an image in low resolution and reading an image in high resolution and realizes prevention of decrease in frame rate. The layer 21 has a filter region 24 held between the layers 22, 23; an annular surrounding region 25 surrounding the region 24 with a predetermined distance therefrom; and an annular connecting region 26 connecting an end part 24e on the substrate 4 side of the region 24 and an end part 25e on the substrate 4 side of the region 25 to each other. Inclusion of a tertiary amine as a catalyst dramatically increases production throughput. The wedge has longitudinal ridges on its inner surface and inwardly tapered edges at its end which is driven into the tube hole such that the tube may be readily inwardly collapsed. Heat transfer fluid is circulated through the cabinet and contacted with the containers for the complete time it takes for the carriage to complete a full revolution.
