1. A paper feed device having regulation plates that are movable on a paper feed tray for loading paper and regulate edges of the paper, the paper feed device comprising:
a driver that moves the regulation plates to be in contact with edge surfaces of a loaded paper; and
a hardware processor that acquires paper information corresponding to a characteristic of the loaded paper detected by a paper information detector, and causes the driver to move the regulation plates to positions in contact with the edge surfaces of the loaded paper based on the acquired paper information detected by the paper information detector so as to align edges of the loaded paper in an appropriate position,
wherein the paper information includes moisture content, and
the hardware processor sets an interval between the regulation plates of a case where the moisture content is equal to or more than a predetermined value wider than an interval between the regulation plates of a case where the moisture content is less than the predetermined value.
