摘要：
A detector, which is included in a sheet feeding device, a sheet conveying device, an image forming apparatus and an image reading device, contacts and detects a sheet, and includes a base, a sheet contact face to which the sheet contacts, and a coat layer formed on the sheet contact face. A difference Δμ of a static coefficient of friction μs of the coat layer and a kinetic coefficient of friction μd of the coat layer is smaller than and equal to 0.12.
