摘要:
The present invention provides a recording media identifier for identifying types of recording media, and a recording device, provided with a recording media identifier, which records images by printing on recording media. A speckle measuring section of the recording device measures a speckle on a recording medium conveyed on a conveyance path. Types of recording media are detected through correlation of the speckle measured with speckles stored in a storage section, in a manner in which the speckles correspond to types of recording media. Recording and fixing conditions of the recording device are adjusted according to the types of the recording media detected.

An image forming apparatus with an image forming part and a fixing part for fixing images on a recording medium measures, downstream of the fixing part in a transport path, speckles on a recording medium, and generates measured speckle data representing the measured speckles; stores measured speckle data with standard speckle data representing speckles on a recording medium that has not undergone a fixing process; further measures, upstream of the image forming part, measures speckles on a recording medium; and when the stored standard speckle data is the most analogous to speckles measured for the second time, applies corrections in order to compensate for the lengthening of the recording medium by a fixing process to document images formed thereon, and when the stored measured speckle data is the most analogous to speckles measured for the second time, does not perform the corrections in order to compensate for the lengthening.

An image forming apparatus having an image forming part that forms an image on a recording medium measures, downstream of the image forming part in a transport path of the recording medium, speckles on the recording medium, and generates measured speckle data that represents speckles measured; stores the generated measured speckle data in a memory part, further measures, upstream of the image forming part in a transport path of a recording medium, the speckles of the recording medium; determines whether speckle data representing speckles analogous to speckles measured upstream of the image forming part is stored in the memory part, and, in the case where the decision result is affirmative, recognizes that the recording medium for which the speckles have been measured is a recording medium on which an image has been formed on it previous to having speckles measured upstream of the image forming part.

A fixing rotatable member for use in an image forming apparatus such as a copying apparatus or a laser beam printer is disclosed. The fixing rotatable member includes a base member and an elastic layer provided on the surface thereof. The elastic layer is addition type silicone rubber in which resin-like polyorganosiloxane and 0.1 to 2 percent by weight of inorganic fine powder are mixed.

The specification discloses an image forming apparatus which forms a visual image on a belt transfer member by at least one of image forming units and transfers the formed visual image onto a recording medium with the aid of the belt transfer member. In the image forming apparatus, the belt transfer member includes an endless belt wound on a plurality of tension rolls. A bending member, which bends the endless belt toward the inside of a tangential line connecting points on the outer circumferences of a couple of tension rolls, and locates the bent endless belt inside the tangential line, is additionally provided outside the endless belt located between at least the couple of adjacent tension rolls. An image forming unit may be additionally provided within an outside bending concave region of the endless belt, which is bent by the bending member and the tension rolls adjacent to the bending member.

A fixing apparatus includes a fixing member and a heating unit. The fixing member forms a nip to convey a recording member which has an unfixed toner thereon. The toner on the recording medium is spherical. The heating unit is provided upstream of the nip in the moving direction of the recording medium, and does not come into contact with the recording medium. The fixing apparatus may include a control means for controlling the heat given from the heating unit to the recording medium.

The electromagnetic induction heating device has a simple construction, holds an object to be heated in a favorable heating condition while effectively suppressing the irregularities of heat generation of the object to be heated, and reduces an energy consumption. The electromagnetic induction heating device which heats the object to be heated provided with at least an electromagnetic induction heat generating layer includes a magnetic core made of magnetic material which is disposed in such a manner that it faces the electromagnetic induction heat generating layer of the object to be heated in an opposed manner, and an exciting coil which is wound around the magnetic core and generates a fluctuation magnetic field which penetrates the electromagnetic induction heat generating layer. A movable core which is capable of moving relative to the object to be heated so as to change the intensity of the fluctuation magnetic field which penetrates the electromagnetic induction heat generating layer is provided to at least a portion of the magnetic core. Furthermore, an image recording device is constructed such that the electromagnetic induction heating device is provided for an image carrying body which corresponds to the object to be heated and fixing unit or a pressure device is disposed at the downstream of the electromagnetic induction heating device.
