SHEET FEEDER AND IMAGE FORMING APPARATUS INCORPORATING THE SHEET FEEDER

摘要

A sheet feeder, which can be included in an image forming apparatus, includes a rotary body to contact and feed a recording medium to a downstream side along a sheet conveying path, a friction body disposed facing and contacting the rotary body with the sheet conveying path interposed therebetween, the friction body forming a separation nip region with the rotary body, a receiver to support the friction body at a position opposite to the separation nip region, and multiple projections to guide the recording medium toward the separation nip region. Each of the multiple projections extends toward the rotary body at respective axial ends of the rotary body and has a top face disposed upstream from the separation nip region in a sheet conveying direction between an outer circumferential surface of the rotary body and a surface of the friction body.
