20220100127 | IMAGE FORMING APPARATUS - An image forming apparatus includes a control unit that controls a conveyance velocity of conveying a recording medium by a fixing unit, to form a loop in the recording medium between a transfer nip portion and a fixing nip portion, in which the control unit controls the conveyance velocity to decrease the loop when a rear end of the recording medium reaches a first position that is apart upstream, in the conveyance direction, from a conveying nip portion of a conveying unit, by a distance that corresponds to a circumference length of a pressure-applying rotating member multiplied by an integer. | 2022-03-31 |
20220100128 | FIXING DEVICE INCLUDING HEAT EQUALIZING MEMBER AND IMAGE FORMING APPARATUS - A fixing device includes a heater, a first rotatable member, a second rotatable member, and a heat equalizing member. In a case that a region including a center of the heat equalizing member with respect to a longitudinal direction is a first region, a region closer to an end of the heat equalizing member than the first region is with respect to the longitudinal direction is a second region, and a region closer to the end of the heat equalizing member than the second region is with respect to the longitudinal direction is a third region. When the heat equalizing member has thermal capacities per unit length in the first region, the second region, and the third region are Cα, Cβ and Cγ, respectively, Cα, Cβ and Cγ satisfy the following relationship: | 2022-03-31 |
20220100129 | IMAGE FORMING APPARATUS AND METHOD FOR CONTROLLING IMAGE FORMING APPARATUS - A second heater has such an output that a peak position in a particular direction is located within a largest sheet area. The largest sheet area is an area in which a heating member contacts a sheet having a largest size in the particular direction that is conveyable through a fixing device. A first sensor detects temperature of a center area. A second sensor detects temperature at an outside position in an end area. The outside position is outside the largest sheet area in the particular direction. A controller controls a first heater such that a first detection temperature detected by the first sensor becomes a first target temperature; controls the second heater such that a second detection temperature detected by the second sensor becomes a second target temperature; and determines the second target temperature based on an edge position of a sheet relative to the peak position. | 2022-03-31 |
20220100130 | HEATING DEVICE, IMAGE PROCESSING APPARATUS,AND METHOD FOR CONTROLLING HEATING DEVICE - A heating device includes a belt, a heater that is in contact with an inner surface of the belt and divided into heater blocks in a width direction thereof, a pressing member that presses a sheet against the belt, a temperature sensor disposed on each of a number of the heater blocks that is at least one-half of the total number thereof, and a processor configured to select one or more of the heater blocks based on a width of the sheet, and select one or more temperature sensors disposed on one or more of the selected heater blocks having the non-paper passing region and control electric power supplied to said one or more of the selected heater blocks to protect against an excessive temperature rise in the non-paper passing region based on temperatures detected by the temperature sensors. | 2022-03-31 |
