description PROBLEM TO BE SOLVED: To provide a cleaning device and a cleaning method for an inkjet head, which when a large-size inkjet head having a nozzle surface of elongated dimensions is subjected to non-contact cleaning in which the nozzle surface is brought into contact with liquid only, enable high-quality cleaning of the nozzle surface to be surely performed, without attaching and leaving a stain and liquid to and in any parts around the nozzle surface.SOLUTION: A cleaning device 100a for an inkjet head 1 comprises: a base 3 including an upper surface 31 for forming a liquid reservoir space by opposing to a nozzle surface 11 when cleaning the nozzle surface 11 and a plurality of liquid recovery holes 32 which are opened in on the upper surface 31 and are aligned along the longitudinal direction of the nozzle surface 11; and a recovery facilitating member 4 arranged in the plurality of liquid recovery holes 32 so as to be exposed to the upper surface 31. An upper end surface 41 of the respective recovery facilitating members 4 projects from the upper surface 31 of the base 3, and its projection quantity is not uniform in the whole of the recovery facilitating members 4, and at least one recovery facilitating member 4 with maximum projection quantity is present.SELECTED DRAWING: Figure 1 【課題】ノズル面の寸法が長大化された大型のインクジェットヘッドに対して、ノズル面に液体のみを接触させる非接触洗浄を行う場合に、ノズル面の周囲にある部分に汚れや液体が付着、残存しないようにして、ノズル面の高品質の洗浄を確実に行うことが可能なインクジェットヘッドの洗浄装置と洗浄方法を提供する。【解決手段】インクジェットヘッド１の洗浄装置１００ａは、ノズル面１１の洗浄時に、ノズル面１１と対面して貯液空間を形成する上面３１と、上面３１で開口し、ノズル面１１の長手方向に沿って並ぶ複数の液体回収孔３２とを含む基台３と、上面３１に露出するように複数の液体回収孔３２に配置される回収促進部材４とを備える。各回収促進部材４の上端面４１は、基台３の上面３１から突出しており、その突出量は回収促進部材４全体で一様ではなく、突出量が最大となる回収促進部材４が少なくとも１つ存在する。【選択図】図１
