A wobble detection device (100) includes a sensor unit (10). The sensor unit (10) includes a one-dimensional image sensor (160) and a one-dimensional image sensor (170) arranged side by side in an auxiliary scanning direction so that their corresponding pixels coincide with each other in a main scanning direction, and acquires an image of an object moving in the auxiliary scanning direction as one-dimensional data. The wobble detection device makes a comparison of data corresponding to the same image region by using one-dimensional data (S 1 ) acquired by the one-dimensional image sensor (160) and one-dimensional data (S 2 ) acquired by the one-dimensional image sensor (170) and thereby detects a movement amount of the image in the main scanning direction between a time when the one-dimensional data (S 1 ) used for the comparison was acquired and a time when the one-dimensional data (S 2 ) used for the comparison was acquired.
