A fastener cartridge can comprise a cartridge body including a plurality of fastener cavities and a plurality of fasteners removably stored therein. The fastener cartridge can further comprise a firing member including a first ramp surface and a second ramp surface which can be configured to co-operatively lift and eject the fasteners from the fastener cavities. The first ramp surface can initially lift the fasteners. The second ramp surface can then complete the lift of the fasteners. In such circumstances, the fasteners can be transferred from the first ramp surface to the second ramp surface of the firing member. In various circumstances, the first ramp surface and/or the second ramp surface can directly engage the fasteners. In other circumstances, the fastener cartridge can include fastener drivers which are directly lifted by the first ramp surface and/or the second ramp surface. The fastener cartridge can further include an anvil.
