An image forming apparatus capable of incorporating a DF, an ADF or an RDF includes a digitizer for designating at least one area of an original, an image forming unit for forming an original image of the designated area on a transfer sheet, and a control section for adding a specific image to the designated area. The control section also allows a multi-copy or a two-sided copy operation for a plurality of designated areas with different colors. The apparatus also includes a memory, the area designation data of which is retained whether reset by a reset key or upon a power ON operation. In this case, only the designated areas are reset. The apparatus further includes a middle tray and a second sheet feeder, which are selectively used according to the types of sheets.

A coordinate input apparatus (editor) of a copying apparatus and the like includes: a tablet to output a signal indicative of a position which is arbitrarily designated; a pointing device to designate an arbitrary point on the tablet; a recognizing circuit to recognize the positions in the X and Y directions of the point designated by the pointing device; a data memory to store the positions of the designated point; a controller which, when a special area on the tablet is designated by the pointing device, allows the signal indicative of the special area to be output; and a correcting circuit to correct the range of the special area. The positions of the designated point in the X and Y directions are detected a plurality of times and compared. The input coordinate data is discriminated by the result of the comparison to see if it is valid or invalid. When the input data is valid, a copying operation is performed. When it is invalid, the copying operation is stopped and the fact that the input data is improper is displayed by an LED indicator and a buzzer is activated. With this apparatus, the coordinate data can be accurately input from the editor and also the accurate trimming or masking of the image can be realized without an erroneous input operation.

A fixing device includes: a rotatable endless fixing belt; a nip forming member arranged inside the fixing belt; a facing rotating body that abuts the nip forming member via the fixing belt to form a nip portion with the fixing belt; a heat source that directly heats up the fixing belt at a portion other than the nip portion; and a supporting member that supports the nip forming member. The fixing device conveys a recording medium carrying an unfixed image to the nip portion to fix the unfixed image to the recording medium, and the supporting member includes a rising portion extending in an abutting direction of the facing rotating body against the fixing belt and having a tip close to an inner circumferential surface of the fixing belt, and is set to have a section modulus of 200 mm3 or higher.

A fixing device includes a fixing rotator, a heat source, a controller, a pressure rotator, and a nip formation pad. The controller controls the heat source such that a temperature of the fixing rotator is equal to a preset fixing temperature. The nip formation pad abuts the pressure rotator via the fixing rotator and forms a nip between the fixing rotator and the pressure rotator. When a print time of a previous job is longer than a prescribed time A and a next job is started within a prescribed time B after an end of the previous job, the controller corrects the preset fixing temperature during a time from a start of the next job to an entry of a print sheet into the nip and during a time from the entry of the print sheet into the nip to a lapse of a prescribed time C after the entry.

According to one embodiment, contactless power transfer apparatus includes: transmission coil; primary capacitor; reception coil opposing transmission coil through gap; and secondary capacitor. Specification of frequency of the transmission coil and that of the reception coil are equal. At least one of electrical power specification and gap length specification of the transmission coil differ from the reception coil. When the electrical power specification of the power transmission coil differ from that of the power reception coil, the power is supplied from the transmission coil to the reception coil by using smaller one of the power of the transmission coil and of the reception coil as maximum power. When the gap length specification of the transmission coil differs from that of the reception coil, the transmission coil opposes the reception coil through the gap length, which is the specification of the transmission coil.

A fixing device including a fixing member, an opposing member, a plurality of heat sources, and a voltage detector. The opposing member is disposed opposite the fixing member to contact the fixing member to form a nip portion at which an unfixed image on a recording medium is fixed. The plurality of heat sources heats the fixing member. The voltage detector detects an applied voltage of at least one of the plurality of heat sources. Upon detection of the applied voltage of the heat sources by the voltage detector, a voltage is applied to at least one of the heat sources.

A fixing device capable of incorporating in an image forming apparatus includes a belt unit including a rotatable elastic endless belt having a sleeve shape without a driving shaft and a nip forming member disposed contactable against an inner surface of the endless belt, and a pressing member to form a nip contact portion through which a recording medium passes by pressing against the nip forming member via the endless belt. The endless belt is configured to be removable from the fixing device without contacting the endless belt.

A spark plug (1) includes a center electrode (5), an insulator (2), a metallic shell (3), a ground electrode (27), and a noble metal tip (32) provided on at least one object member of the center electrode and the ground electrode. One end surface of the noble metal tip is joined to the object member via a fusion zone (35). The fusion zone includes a first fusion zone (351) formed through radiation of a laser beam or the like to the boundary between the object member and the one end surface of the noble metal tip along a perimetrical direction of the noble metal tip, and a second fusion zone (352) formed through radiation of the laser beam or the like from the side from which the laser beam or the like has been radiated in forming the first fusion zone, and intersecting with the first fusion zone.
