<p>PROBLEM TO BE SOLVED: To provide a sheet feeding device capable of suppressing occurrence of double feed of sheets and a rubbing noise due to variation of a feeding position and capable of realizing stable sheet feeding operation, and an image formation device including the same.SOLUTION: The sheet feeding device includes: a lift plate; feeding means; energization means; eccentric cams; and cam followers. The eccentric cam has a first cam part, and a second cam part in which a rate of change of an eccentric radius per unit rotation angle is different from that of the first cam part, and the first cam part and the second cam part are formed into each eccentric cam so as to be symmetrical with respect to the feeding means. The cam follower has a first contact part with which the first cam part is in contact and a second contact part with which the second cam part is in contact. When the lift plate is lifted, after a new contact point is generated between the second cam part and the second contact part, the contact point between the first cam part and the first contact part is separated.</p> |
