Sheet carrying device and image forming apparatus

A sheet carrying device which carries a sheet, the sheet carrying device comprising:

• a first carrying unit;
• and
• a second carrying unit,
• wherein the sheet is transferred from the first carrying unit to the second carrying unit,
• wherein the first carrying unit includes
• a first rotary body,
• a first driving unit that outputs a driving force for driving to rotate the first rotary body at a first peripheral speed,
• a one-way clutch that transmits the driving force output by the first driving unit to the first rotary body only in a direction in which the first rotary body carries the sheet,
• a second rotary body that is driven to rotate by the first rotary body via the sheet while the sheet is interposed between the first rotary body and the second rotary body,
• wherein the second carrying unit includes
• a third rotary body that rotates at a second peripheral speed equal to or faster than the first peripheral speed,
• a second driving unit that outputs a driving force for driving to rotate the third rotary body at the second peripheral speed equal to or faster than the first peripheral speed,
• a fourth rotary body that carries the sheet while the sheet is interposed between the third rotary body and the fourth rotary body,
• a third driving unit that outputs a driving force for driving to rotate the fourth rotary body at a third peripheral speed equal to or faster than the second peripheral speed, and
• a torque limiter that has a slip torque smaller than a torque for carrying the sheet while the sheet is interposed between the third rotary body and the fourth rotary body and cuts off the driving force output by the third driving unit while the sheet is interposed between the third rotary body and the fourth rotary body so as to be carried.
