摘要:
An image heating apparatus is for heating an image formed on a recording material, and has a first roller, a second roller cooperating with the first roller to form a conveying nip portion for passing the recording material therethrough, and heating means for heating the first roller from the outer peripheral surface side thereof, and each of the first roller and the second roller has an adiabatic layer formed of a porous ceramics material and an elastic layer disposed outside the adiabatic layer. Thereby, consumed power during the passing of the recording material can be suppressed.

An image heating device for heating a toner image while nip-conveying a recording material, in a nip, on which the toner image is carried, includes a heating member; and a pressing roller, including an elastic layer, for forming the nip in contact with the heating member. The elastic layer of the pressing roller includes a thermosetting silicon rubber containing a thermal conductive filler. The thermosetting silicon rubber includes pore portions formed with resin microballoons and a pore connecting portion for connecting the pore portions. The elastic layer has a thermal conductivity of 0.15 W/mK to 0.5 W/mK.

The present invention relates to an image heating apparatus in which a nip portion is formed by a heating unit, which includes a flexible sleeve and a heater, and a pressure roller. The position of the heating unit is appropriately maintained by pressing the heating unit against the pressure roller using a pressure member so that the heating unit can contact two or more portions of a downstream side rim of a groove arranged on a frame that holds the heating unit, even when the pressure roller is rotated.

There is provided a map information providing technology that can keep map information very fresh at all times.A map information management system has a map to be updated DB for storing map data to be updated that is used to update and maintenance, a map to be provided DB for storing map data to be provided that is distributed, an updated data DB for storing updated data for updating the map data to be provided, a map DB update means for updating the map data to be updated when the updated data for updating the map data of the map data to be updated DB is input, an updated data creation mean for creating the differential data before and after it is updated by the updated data and storing the differential data in the updated data DB as the updated data, and a data distribution means for extracting the map data to be provided or the updated data stored in the map to be provided DB when it receives a request to distribute the map data or the updated data from a destination system and distributing it to the destination system.
摘要:
A fixing device for fixing on a recording material a toner image formed on the recording material includes a flexible sleeve including a resinous base layer, a parting layer and an adhesive layer for bonding the base layer and the parting layer; a heater contacted to an inner surface of the sleeve; a pressing member for forming a nip, in which the recording material on which the toner image has been formed is nipped and conveyed, between itself and the sleeve to which the heater is contacted; a voltage applying member for applying a voltage, of a polarity identical to a polarity of toner; and a grounding member, contactable to the recording material in a nipped state in the nip, for grounding the recording material. In a thickness direction of the layers, an electric resistance of the adhesive layer is larger than that of the parting layer and the electric resistance of the parting layer is larger than that of the base layer. The voltage applying member applies the voltage to the sleeve in contact with the base layer.

The present invention relates to an image heating apparatus in which a nip portion is formed by a heating unit, which includes a flexible sleeve and a heater, and a pressure roller. The position of the heating unit is appropriately maintained by pressing the heating unit against the pressure roller using a pressure member so that the heating unit can contact two or more portions of a downstream side rim of a groove arranged on a frame that holds the heating unit, even when the pressure roller is rotated.
