An image reading device includes a document conveying device, a first reading module and a control portion. When initial white reference data, that is, an initial value of white reference data, is acquired, the control portion performs white reference data acquisition processing in a plurality of reading modes sequentially, and if it is judged that the white reference data meets a predetermined condition through data judging processing in all the plurality of reading modes, the acquired initial white reference data is set as usable, and if it is judged that the white reference data does not meet the predetermined condition through data judging processing in at least one of the plurality of reading modes, the acquired initial white reference data is set as unusable.
