PROBLEM TO BE SOLVED: To provide a transparent belt to which pressure is applied at a nip part formed by the transparent belt being wound around a transparent roll and through which light from a light source transmits, and suppress scattering of light between the transparent roll and transparent belt compared with a configuration where a base material layer is arranged closest to the transparent roll.SOLUTION: A transparent belt 22 is applied with pressure at a nip part N formed by the transparent belt being wound around a transparent roll 28 and through which a laser beam Bm from a light source 24 transmits. The transparent belt 22 comprises a base material layer 22B, and an elastic layer 22A that is exposed closer to the transparent roll 28 than the base material layer 22B and is elastically deformed more largely than the base material layer 22B at the nip part N.SELECTED DRAWING: Figure 3 【課題】透明ロールに巻き掛けられて形成されたニップ部で加圧され、光源からの光が透過する透明ベルトにおいて、基材層が一番透明ロール側に配置された構成に比べて、透明ベルトと透明ロールとの間における光の散乱を抑制する。【解決手段】透明ベルト２２は、透明ロール２８に巻き掛けられて形成されたニップ部Ｎで加圧され、光源２４からのレーザ光Ｂｍが透過する。さらに、透明ベルト２２は、基材層２２Ｂと、基材層２２Ｂよりも透明ロール２８側で露出されニップ部Ｎで基材層２２Ｂよりも大きく弾性変形する弾性層２２Ａと、を有する。【選択図】図３
