    摘要: PROBLEM TO BE SOLVED: To provide a sheet feeder, capable of lowering a sheet loading member to a sheet loading position quietly when sheet loading quantity is large, and quickly when the sheet loading quantity is small, and an image forming device provided with that.
    SOLUTION: In lowering the sheet loading member toward the loading position, lowering speed of the sheet loading member is controlled by a lowering speed control means 30A comprising an energization mean 38 to energize the sheet loading member in the lowering direction to speed up the lowering speed, and a brake means 35 to restrict lowering speed of the sheet loading member. The sheet loading member with smaller loading quantity is quickly lowered to the sheet loading position by controlling energization force of the energization means 38 of the lowering speed control means 30A in such a way that impact when the sheet loading member reaches the loading position is prescribed size or less, and in such a size that the sheet loading member is lowered to the loading position within prescribed time when the sheet loading member lowers.
