摘要： An image forming apparatus includes paper trays to contain and feed a recording sheet on which a toner image is transferred; status sensors to detect a storage status of the recording sheet contained in the paper trays; a sheet sensor to detect a smoothness of the recording sheet; a memory to store detection values of the smoothness detected by the sheet sensor; a fixing device to heat and press the toner image transferred onto the recording sheet and fix it onto the recording sheet; and a control circuit to determine a target fixing temperature of the fixing device based on the detection values stored in the memory. The control circuit determines the target fixing temperature for successive recording sheets depending on the detected smoothness, and resets the detection values stored in the memory to zero when the status sensors detect a change in the storage status of the paper trays.

摘要： A fixing device includes a rotatable, endless fixing belt; a rotatable contact member configured to contact a circumferential surface of the fixing belt to form a nip in association with the fixing belt; and a heating member disposed at an interior surface of the fixing belt, configured to heat the fixing belt. The heating member includes a multiple heat sources arranged along the width of a sheet of recording media in a direction perpendicular to a sheet conveyance direction. A controller changes an area to be heated by each heat source based on image data and corresponding to an unfixed image on the sheet. The fixing belt is heated by the heating member so that the unfixed image on the sheet that has been conveyed to the nip is fixed onto the sheet at least with heat. The heating member is disposed at a portion other than the fixing nip.

摘要： A fixing device includes a rotatable fuser member, a rotatable pressure member, a heater, a rotary driver, a thermometer, and a controller. The rotatable fuser member is subjected to heating. The rotatable pressure member is disposed opposite the fuser member. The heater heats the fuser member. The rotary driver imparts torque to at least one of the fuser and pressure members. The fuser member and the pressure member are pressed against each other to form a fixing nip therebetween. The thermometer is disposed external to the fixing nip to detect a temperature outside the fixing nip. The controller is operatively connected with the thermometer to control an amount of heat applied to the recording medium through the fixing nip according to the detected temperature, so that the recording medium exhibits a substantially constant post-fixing temperature downstream from the fixing nip.

摘要： An image forming apparatus includes an image forming device to form a toner image on a recording medium under a prescribed image forming condition, a fixing device to fix the toner image borne on the recording medium thereonto by heating the recording medium based on target fixing temperature, and a detector to detect a type of recording medium. The type is used in setting at least one of the image forming condition and the target fixing temperature. The inequality Tb>Ta is established when Ta represents a time period needed to reach a setting of fixing temperature allocated to the recording medium with its tip detected by the detector after detection of the tip and Tb represents a time period needed for the recording medium with its tip detected by the detector to reach the fixing device after detection of the tip.

摘要： A fixing control device includes a power distribution controller that adjusts a power distribution time period when the power is distributed to plural heater elements per control cycle, a turn on time determining member that determines a time when each of the plural heater elements is turned on based on a duty ratio between the power distribution time period and the control cycle, and a soft operation controller that either gradually starts or stops heating each of the plural heater elements during a soft start or stop period, respectively. One of the soft start and stop periods for one of the plural heater elements is decreased not to overlap with another one of the plural heater elements.
