Title: Image forming apparatus
Inventor: ITO HIROTO
IPC: G03G15/20
Filed: 2020-09-03
Abstract: To provide an image forming apparatus that can detect, with a thermistor, a change in temperature of a heater occurring due to multi-feed of recording materials and correctly prevent the increase in temperature of the heater.SOLUTION: A control unit acquires the temperature of a thermistor every n seconds from when a recording material enters a fixing nip part until when the recording material passes through the fixing nip part (S7, S8), and determines "detected temperature inclination ΔTn+1" in accordance with the acquired "detected temperature Tn" and "detected temperature Tn+1" (S9). When the "detected temperature Tn+1" is equal to or higher than "predetermined temperature Ta" (No in S10), the control unit determines that there is a local change in temperature of a heater caused by multi-feed of recording materials, acquires "stored temperature inclination ΔT0" from an IC memory, and changes a reference temperature (S14). Upon occurrence of the multi-feed of recording materials, the control unit changes the reference temperature in accordance with the "stored temperature inclination ΔT0" stored in the IC memory to prevent an increase in temperature of the heater, and thus the heater is not heated to such a temperature that the heater itself is damaged and part of a fixing film is melted.SELECTED DRAWING: Figure 5

Abstract: To provide a combustible gas ejection prediction device that can effectively predict the phenomenon that combustible gas is released from groundwater and ejected to the surface of the earth when the atmospheric pressure drops.SOLUTION: A combustible gas ejection prediction device 1 includes an observation well 2, a gas concentration meter 21, a pressure gauge 22, and a data processing device 201.
