Abstract
A disclosed sheet carrying device includes a first carrying unit that includes a first rotary body, a first driving unit outputting a driving force at a first peripheral speed, a one-way clutch transmitting the driving force only in a sheet carrying direction, and a second rotary body driven by the first rotary body via the sheet; and a second carrying unit including a third rotary body rotating at a second peripheral speed being the first peripheral speed or more, a fourth rotary body carrying the sheet with the third rotary body, a second driving unit outputting a driving force for driving the fourth rotary body at a third peripheral speed being the second peripheral speed or more, and a torque limiter having a slip torque smaller than a sheet carrying torque and cutting off the driving force while the sheet is interposed between the third and fourth rotary bodies.
