摘要： In an image forming apparatus in which when separating a recording material from a recording-material conveying sheet, the recording-material conveying sheet is pressed and deformed by a pressing member, the pressing member has a convex curved portion contacting the recording-material conveying sheet in a direction orthogonal to the moving direction of the recording-material conveying sheet. It is thereby possible to sufficiently deform the recording-material conveying sheet while preventing it from being permanently deformed or broken.
