Sheet adsorption device, transport device, and image forming apparatus

摘要

A sheet adsorption device includes a sheet adsorbing surface (41), a suction hole (42) disposed on the sheet adsorbing surface, and a flow path shifting unit (70) that shifts between a first state and a second state of a communication flow path that is communicated with the suction hole (42) in accordance with existence of a sheet that covers the suction hole (42). The cross-section area of a flow path in the second state is smaller than that in the first state and the communication flow path (70) is not closed in the second state.
