Media processing apparatus, image forming apparatus, and image forming system

Abstract

A media processing apparatus includes: an internal tray; an ejection tray; a first conveyor to convey a sheet medium in a first conveyance direction leading to the ejection tray via the internal tray; a second conveyor to convey the medium in a second conveyance direction; a binder including a pair of clampers to clamp sheet media stacked on the internal tray and being switchable among an out-of-contact state in which the clampers are out of contact, a clamping state in which the media are clamped by the clampers, and a binding state in which the media are pressed and bound by the clampers. The circuitry switches the binder into the clamping state when an (N+1)-th sheet medium is conveyed in the first direction while contacting an N-th sheet medium in a state in which N sheets of sheet media are stacked on the internal tray, N being a natural number.
