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. |

1. A recording medium conveyor comprising:
a driving source to generate a driving force; a first rotary unit rotated by the driving force, the first rotary unit including
a driving gear to rotate by receiving the driving force,a driving shaft to rotate together with the driving gear, andmultiple driving rotary bodies disposed spaced apart from each other on the driving shaft, the multiple driving rotary bodies to integrally rotate with the driving shaft; a second rotary unit disposed facing the first rotary unit and rotated by the first rotary unit, the second rotary unit including
a driven gear meshed with the driving gear,a driven shaft to rotate together with the driven gear,multiple driven rotary bodies rotatably supported by the driven shaft, disposed spaced apart from each other on the driven shaft, and pressed against the multiple driving rotary bodies, andmultiple stiffening rotary bodies disposed spaced apart from each other on the driven shaft, disposed between adjacent two of the multiple driven rotary bodies, and having a diameter greater than an outer diameter of each of the multiple driven rotary bodies, the multiple stiffening rotary bodies to integrally rotate with the driven shaft, a gear ratio between the driving gear of the first rotary unit and the driven gear of the second rotary unit being adjusted such that a peripheral speed of each of the multiple driving rotary bodies is equal to a peripheral speed of each of the multiple stiffening rotary bodies. |
