20200233348 | HEATING APPARATUS INCLUDING A PLURALITY OF HEAT GENERATION MEMBERS, FIXING APPARATUS, AND IMAGE FORMING APPARATUS - The heating apparatus including a plurality of heat generation members including first, second and third generation members, the second heat generation member and the third heat generation member having lengths in a longitudinal direction shorter than a length of the first heat generation member, the heating apparatus including first, second, third, and fourth contacts, and a first switching unit configured to bring an electric path between the second contact and the fourth contact into one of a connecting state and an open state. | 2020-07-23 |
20200233349 | IMAGE FORMING APPARATUS CONTROLLING POWER SUPPLY PATH TO HEATER - The image forming apparatus includes a fixing apparatus including a heater that includes at least two heat generation members, the fixing unit configured to fix an unfixed toner image formed on a sheet by an image forming unit, a heat generation member switching device configured to switch a power supply path so that electric power can be supplied to one of the heat generation members, a CPU configured to control switching the power supply path by the heat generation member switching device based on a number of shorter width sheets in a longitudinal direction continuously printed in a case where a plurality of mixed sheets including longer width sheets and the shorter width sheets. | 2020-07-23 |
20200233350 | HEATING APPARATUS AND IMAGE FORMING APPARATUS FOR CONTROLLING CONDUCTION TO HEAT GENERATION MEMBER - In a case where a drive instruction signal in a high level for placing a first triac provided to correspond to a heat generation member in a conduction state is output from a CPU, the first triac is placed in a conduction state after a second triac provided to correspond to a heat generation member is prohibited from being in a conduction state. In a case where a drive instruction signal in a low level for placing the second triac in a non-conduction state is output from the CPU, the state in which the second triac is prohibited from being in the conduction state is released after the first triac is placed in the non-conduction state. | 2020-07-23 |
