CALCULATING DEVICE AND IMAGE FORMING APPARATUS |
| 摘要 |
A calculating device for calculating a lifetime of a rotatable member for heating a toner image on a recording material at a nip includes a first acquiring portion configured to acquire a rotation time of the rotatable member; an accumulating portion configured to accumulate the rotation time of the rotatable member acquired by the first acquiring portion; and a second acquiring portion configured to acquire a temperature of the rotatable member. The accumulating portion accumulates the rotation time of the rotatable member acquired by the first acquiring portion after weighting is made on the basis of the temperature of the rotatable member acquired by the second acquiring portion. |
