Title: Image forming device
Inventor: NITTO TAIGA
IPC: G03G21/20
Filed: 2019-02-07
Abstract: To shorten FPOT and suppress the wear of a fixing unit.SOLUTION: When a printing indication is received from a user (Yes in S10), a control unit 80 determines required nip pressure that corresponds to a temperature difference T (S14). The control unit 80 also determines upper-limit nip pressure that corresponds to the total travel distance P of a fixing belt 51 (S16). When the required nip pressure is lower than or equal to the upper-limit nip pressure (Yes in S17), the control unit 80 sets nip pressure to the required nip pressure (S18) and starts conveyance of paper 21a, 21b to a nip unit N. Meanwhile, when the required nip pressure exceeds the upper-limit nip pressure (No in S17), the control unit 80 sets nip pressure to the upper-limit nip pressure (S19) and starts conveyance of paper 21a, 21b to the nip unit N after elapse of an additional time. Thereafter, when the temperature difference T becomes a prescribed value (Yes in S26), the control unit 80 changes nip pressure to small nip pressure.SELECTED DRAWING: Figure 14
