Transport device, image forming apparatus, and image reading apparatus

A transport device comprising:

• a first roller that is driven to rotate by a driving section, and transports a recording medium;
• a second roller that includes a second rotating shaft and a second rotating section, and pushes the transported recording medium against the first roller, the second rotating section including a first member that comes into contact with the recording medium, and a second member that comes into contact with the first roller when the recording medium having a predetermined size is transported;
• and
• a measurement unit that measures speed at which second rotating shaft rotates,
• wherein a force with which the first member rotates the second rotating shaft is greater than a force with which the second member rotates the second rotating shaft,
• wherein the first member is fixed to the second rotating shaft, and
• wherein the second member slides along the second rotating shaft.
