<p>PURPOSE:To simplify the device, to reduce the load applied on a main driving source, to evade the possibility of misalignment in relationship of positions of a middle heating roll and a sheet carrying movement part due to erroneous operation and to reduce the occurrence of paper-jamming by unnecessitating an exclusive movement mechanism to vertically move the sheet carrying movement part and sensors, etc. CONSTITUTION:The middle heating roll 202 provided to be able to be in contact/ uncontact with an upper and a lower heating rolls 201 and 203 in the fixing device and a sheet carrying part 121 of a suction unit 100 carrying the sheet where a toner image is transferred to this fixing device are connected by an arm 301 and the middle heating roll 202 and the sheet carrying movement part 121 are linked and moved vertically by rotation of a link cam 305.</p> |
