Sheet conveying device and image forming apparatus

An image forming apparatus comprising a sheet conveying device including

• a first sheet conveying unit that is located upstream in a sheet conveying direction and that includes a first driving roller and a first driven roller;
• a second sheet conveying unit that is located downstream in the sheet conveying direction, that includes a second driving roller and a second driven roller, and of which a driving torque is controllable;
• a torque estimation unit that, based upon a first load torque generated at a time that a sheet-like member passes through a first nip between the first driving roller and the first driven roller, estimates a second load torque generated at a time that the sheet-like member passes through a second nip between the second driving roller and the second driven roller;
• and
• a control unit that controls the driving torque such that the second load torque is counterbalanced by applying a counterbalancing torque in synchronization with a timing of entry of the sheet-like member into the second nip.
