摘要:
In an image forming apparatus according to the present invention, a shield plate 202 which is made of a specific material and has a specific thickness is provided between an exciting coil and at least one of a first and a second magnetic field intensity measuring point P1, P2, which prevents a magnetic field of a specific magnetic field intensity or higher from leaking to the outside of the image forming apparatus or alleviates the effect of the magnetic field on the circuits in the apparatus or optionally installed devices.
摘要:
A distance defined by expression 2 is secured between the exciting coil and the protection cover. This not only prevents a magnetic field with a specific magnetic field intensity or higher from leaking to the outside but also reduces the effect on the circuits in the apparatus or optionally installed circuits (including a printer controller and a FAX controller).
摘要:
An excitation coil and/or a core member, which has a characteristic frequency other than frequencies used, is employed. Thereby, resonance is prevented between adjacent coils or between a coil and an adjacent component such as a core member.

A technique of reducing temperature unevenness in a heating member which heats a heating target member while reducing heat capacity of the heating member in a fixing device for an image forming apparatus is provided. The fixing device has a heating member having diamond fine particles dispersed and contained at least in its surface layer, a pressurizing member which is pressed in contact with the heating member and nips and carries a sheet in collaboration with the heating member, and a heating unit which heats the heating member.

An image formation apparatus is provided for supporting adjustment of the distance between a heat roller and a heating unit for heating the heat roller, thereby supporting adjustment of supplied power to the heating unit. The image formation apparatus includes a heat roller for clamping paper with a toner image formed thereon with a pressurization roller; a heating unit being placed facing the heat roller for heating the heat roller; a power supply unit for supplying power to the heating unit; an acquisition unit for acquiring a power value based on the power supplied from the power supply unit; a comparison unit for making a comparison between the power value acquired by the acquisition unit and a predetermined power value; and a display unit for displaying information concerning adjustment of a distance from the heat roller to the heating unit based on the comparison result of the comparison unit.
摘要:
A heat roller of a fixing apparatus according to an embodiment of the invention has a slidable metal belt on an outer side of an elastic roller. The width of the metal belt is made larger than that of the elastic roller. Flanges, each of which regulates a sliding movement of the metal belt by being in contact with an edge of the metal belt, are provided on both sides of a press roller opposite the metal belt.
