Image forming apparatus

An image forming apparatus, comprising:

• an image forming device configured to form an image on a sheet;
• a motor configured to generate a driving force;
• a driving gear including a first coupling, the driving gear being rotatable by the driving force from the motor;
• a first roller configured to convey the sheet toward the image forming device;
• a transmission gear meshed with the driving gear, the transmission gear being rotatable integrally with the first roller;
• a second roller configured to nip the sheet in conjunction with the first roller and rotate to convey the sheet toward the image forming device;
• an urging member urging the second roller toward the first roller;
• and
• a joint shaft connected to the first coupling at one end thereof in an axial direction,
• wherein the second roller includes a second coupling arranged concentrically with a rotation shaft of the second roller, the second coupling being configured to transmit the driving force from the driving gear to the second roller, the second coupling being connected with the other end of the joint shaft in the axial direction, the second coupling in conjunction with the first coupling and the joint shaft forming a universal joint.
