Title: Image forming apparatus
Inventor: SAKO TADAO
IPC: G03G21/00
Filed: 2019-05-17
Abstract: To automatically eject a recording material to a loading unit without a danger of causing a failure in an image reading device when a failure occurs in a cooling device.SOLUTION: In a case where a recording material cooling device fails, when the temperature of a recording material is higher than an operation guarantee temperature, which is likely to cause a failure in an image reading device (No in S4), power supply to the image reading device is turned off (S5). Turning off the power supply can set a temperature that is likely to cause a failure in the image reading device to a storage guarantee temperature that is higher than the operation guarantee temperature. When the temperature of the recording material is higher than the storage guarantee temperature (No in S6), conveyance of the recording material is stopped and the recording material is prevented from passing through the image reading device until the temperature of the recording material falls to the storage guarantee temperature or below (S7). That is, when the recording material cooling device fails, the temperature of the recording material is decreased to a temperature that is not likely to cause a failure in the image reading device, and subsequently the recording material is allowed to pass through the image reading device. Thus, the recording material left unconveyed in a conveyance path can be automatically ejected without a danger of causing a failure in the image reading device.SELECTED DRAWING: Figure 6
