Abstract
Provided are: a sheet feed device that is capable of suppressing the occurrence of a sheet feeding fault by changing the pressing contact force of a retard roller against a feed roller; and an image formation device equipped with the same. This sheet feed unit () is provided with: a pickup roller (); a feed roller (); a retard roller (); a holding member () that holds the retard roller (); a first biasing member () that biases the holding member (); and a pressing contact force changing mechanism () that changes the pressing contact force of the retard roller () against the feed roller (). The pressing contact force changing mechanism () has: a rotary shaft () disposed parallel to the axial direction of the retard roller (); a cam member () that rotates with the rotary shaft (); and a movable member () that contacts the cam member (), moves in the axial direction in conjunction with the rotation of the cam member (), and changes the biasing force generated by the first biasing member ().
