Abstract:
1. An image forming apparatus, comprising: a cooling device; an image formation processing unit; a main control unit configured to be cooled by the cooling device, and including a main image formation control unit, an abnormality detecting unit, an abnormality information writing unit, an abnormality information determining unit, and a start-up aborting unit, the main image formation control unit configured to control the image formation processing unit, the abnormality detecting unit configured to detect an abnormality in the cooling device, the abnormality information writing unit configured to store information informing a presence of the abnormality in the cooling device into a non-volatile memory when the abnormality detecting unit detects the abnormality in the cooling device, the abnormality information determining unit configured to determine whether the information informing the presence of the abnormality in the cooling device is stored in the non-volatile memory in a case where start-up processing of the image formation processing unit is started as power supply to the main control unit and the image formation processing unit is started, the start-up aborting unit configured to abort the start-up processing of the image formation processing unit in a case where the information informing the presence of the abnormality in the cooling device is stored in the non-volatile memory; a secondary control unit including a secondary image formation control unit and a power supply control unit, the secondary image formation control unit configured to control the image formation processing unit, the power supply control unit configured to stop power supply to the main control unit in a case where the abnormality detecting unit detects the abnormality in the cooling device; and a changeover unit configured to connect the image formation processing unit to the main image formation control unit in a case where power is supplied to the main control unit and to connect the image formation processing unit to the secondary image formation control unit in a case where the power supply to the main control unit is stopped by the power supply control unit in the secondary control unit.
