Claims

[Scope of utility model registration request]

In a fixing device comprising at least a pair of rolls that can be rolled into contact with each other and which heats and fuses a toner image while sandwiching a transfer paper at the rolling contact portion, the pair of rolls are in pressure contact with each other; a contacting/separating mechanism that allows the rolls to move freely between a separation position where the rolls are separated from each other at maximum; and a holding mechanism that allows the pair of rolls to be held at a contact position where both of them are in contact with each other in the contacting/separating movement path. A fixing device comprising:
