A fixing apparatus includes: two rotatable members, for forming a nip, including a region where an outer diameter is increased from a longitudinal central portion toward a longitudinal end portion; a heater; and a controller for controlling a heat generation distribution of the heater. The controller is capable of controlling the heater so that the heat generation distribution of the heater is such that a heat generation amount at the longitudinal end portion is larger than that at the longitudinal central portion in a period from start of the heater until the recording material reaches the nip. A ratio of the heat generation amount at the longitudinal end portion to that at the longitudinal central portion is larger when a cumulative amount of use of the fixing apparatus is larger than a predetermined amount than when the cumulative amount of use is smaller than the predetermined amount.

The present invention provides an image forming apparatus including an upstream conveying portion, a downstream conveying portion, and a loop detector, wherein the image forming apparatus further includes a driving portion which moves the contact portion to a projecting position where the sheet conveying path is in contact with a conveyed sheet and to a retracted position where the sheet conveying path is not in contact with the conveyed sheet, and a controlling portion which controls the driving portion such that the contact portion is moved from the projecting position to the retracted position before a tip end of a sheet which enters the sheet conveying path from the upstream conveying portion reaches the contact portion.

A cylindrical heat generating belt in an image heating apparatus includes a heat generating layer, in which an electroconductive filler is dispersed in a resin material, for generating heat by being supplied with electric power; and a surface parting layer. The heat generating layer has a sheet resistance, with respect to a generatrix direction of the heat generating belt, which is larger than that with respect to a circumferential direction of the heat generating belt.

Corrected power for compensating for a reduction in the temperature of an endless belt that accompanies the entry of a recording material into a fixing nip portion is adjusted by correcting the power supplied to a fixing unit when the recording material enters the fixing unit with a correction power based on a difference between the update time of a power updating period and the time of the entry of the recording material.
摘要:
In a system having plural terminals including terminals A, B, when the terminal A is editing a data object and editing information is shared among the plural terminals, if the terminal B performs a changeover operation of displayed page, the editing operation in the terminal A is cancelled, and the editing information is deleted in the other terminals. In the terminal A, the editing information by that time is held, and when the data object is restored, the held editing information is transmitted to the other terminals. Then the initial display status is restored in the other terminals.

The image forming apparatus includes a fixing portion, a temperature detection element, and a power control portion, wherein the power control portion is capable of setting a first power supply control mode for supplying power according to the detected temperature for each one control cycle, a second power supply control mode for supplying power according to the detected temperature for each one control cycle and a third power supply control mode for supplying predetermined power, and switches, immediately before a leading edge of the recording material enters the fixing portion, a state of supplying the power in the first power supply control mode to a state of supplying the power in the second power supply control mode, and then switches the state of supplying the power in the second power supply control mode to a state of supplying the power in the third power supply control mode.
摘要:
The image forming apparatus, in the case where image forming is performed on a recording medium whose size covers a position of a second temperature detection element perpendicularly disposed to the recording medium conveyance direction, when the detected temperature rises to a predetermined temperature during execution of the first power supply control, a first power supply control is switched to a second power supply control. In the case where image forming is performed on a recording medium whose size does not cover a position of the second temperature detection element, when the detected temperature rises to a predetermined temperature during execution of the first power supply control, a conveyance control portion executes a control for extending the conveyance interval of the recording medium. Thus, an unduly large temperature rise in the non-sheet passing portion is prevented, and a good quality image can be provided without glossy unevenness in one sheet.
