Abstract
A recording medium conveyor includable to an image forming apparatus includes a driving source, a first rotary unit, and a second rotary unit. The first rotary unit includes a driving gear, a driving shaft rotating with the driving gear, and multiple driving rotary bodies disposed on the driving shaft. The second rotary unit disposed facing the first rotary unit includes a driven gear meshed with the driving gear, a driven shaft, multiple driven rotary bodies disposed on the driven shaft, and multiple stiffening rotary bodies disposed between two of the multiple driven rotary bodies and having a diameter greater than an outer diameter of the multiple driven rotary bodies. A gear ratio between the driving gear and the driven gear is adjusted such that a peripheral speed of the multiple driving rotary bodies is equal to a peripheral speed of the multiple stiffening rotary bodies.
