Abstract
A measuring device of a length of a recording material includes: a rotary unit that rotates while coming into contact with the recording material; a pulse signal output unit that outputs a pulse signal in response to a rotation angle of the rotary unit; first and second detection units that detect the recording material; and a calculation unit that calculates a length of the recording material. The calculation unit calculates a piece of the length of the recording material corresponding to a time below pulse interval of the pulse signal and then calculates the total length in the transport direction of the recording material.
