加熱装置及び画像形成装置
Document Type and Number:
Japanese Patent JP5839821
Kind Code:
B2
Abstract:
The heating apparatus includes a first detection part which detects whether or not the power supplied to the heat generation member is in an overpower state by detecting a positive phase of a half wave in an alternating voltage of a commercial power supply applied to the first or the second current path of the heat generation member, a second detection part which detects whether the power supplied to the heat generation member is in an overpower state or not by detecting a negative phase of a half wave in an alternating voltage the commercial power supply applied to the first current path or the second current path of the heat generation member, and a control part which controls itself to stop supplying power from the commercial power supply to the heat generation member in a case where an overpower state is detected by the first or second detection part.
