Abstract
A rotary member apparatus includes a main drive unit configured to apply a driving torque to a photosensitive drum through a drive transfer unit, a torque limiter configured to limit the driving torque transmitted from the main drive unit to the photosensitive drum, a compensation drive unit configured to apply a torque for adjusting an angular velocity of the photosensitive drum, an encoder configured to detect the angular velocity of the photosensitive drum, and a compensation drive controller configured to control the torque applied by the compensation drive unit on the basis of a detection result obtained by the encoder.
