An image reading device includes a reader, an opposing member, and circuitry. The reader is configured to read an image of an object to be conveyed. The opposing member has a plurality of opposing portions that include reference surfaces selectively switchable to be placed at a reading position of the reader. The reference surfaces include two or more identical reference surfaces. The circuitry is configured to determine whether an evaluation reading value of reading values read by the reader on each of the two or more identical reference surfaces is within a prescribed range and perform correction operation of the image reading device with the evaluation reading value within the prescribed range out of the reading values of the two or more identical reference surfaces.

An image forming apparatus includes an oscillator configured to oscillate a laser beam, an irradiation portion configured to radiate the laser beam oscillated by the oscillator to an outside, a light absorption unit configured to absorb the laser beam and to convert the laser beam to heat, and a control unit including at least one processor and at least one memory. The control unit is configured to control the irradiation portion to press the irradiation portion against a workpiece via the light absorption unit and irradiating the workpiece with the laser beam via the light absorption unit, so as to perform image forming processing.

The present invention provides an electrostatic printing apparatus that can produce a conductive transparent electrode substrate for use in an organic EL device or the like, which is inexpensive and highly reliable. The electrostatic printing apparatus of the present invention includes a power supply (13), a conductive ejection unit (11) that ejects an ink for forming an insulating film to a target electrode (22), a control unit (12) that applies a bias voltage to the conductive ejection unit (11), and a pulse control unit (14) that applies a pulse voltage to the target electrode (22).

A wireless IC tag (11) is mounted to a toner cartridge (1), and a reader writer (2) reads and writes data from and to the wireless IC tag (11). The toner cartridge (1) includes plural cartridge contact terminals (12), and a load (13) arranged between the cartridge contact terminals (12). The load (13) corresponds to a type of the wireless IC tag (11). The reader writer (2) includes an antenna coil (21) for wireless communication with the wireless IC tag (11), and plural reader writer contact terminals (22) that contact to the plural cartridge contact terminals (12) respectively when the toner cartridge (1) is mounted to this image forming apparatus. Further, a wireless transmission characteristic of the reader writer (2) is adjusted in accordance with the load (13) electronically connected to the reader writer contact terminals (22).

An image inspection device includes a processor coupled to a sensor. The processor reads, using the sensor, an image formed on a recording material by an image forming device and creates a read image; causes an analysis to detect an abnormality in the read image and creates an analysis result; and creates a normal image file including the read image in which the abnormality has not been detected based on the analysis result.

An image forming apparatus includes a scanner, a printer configured to print an image based on an image read by the scanner, a memory, and a processor. The memory stores a setting value for adjusting positioning of an image to be printed by the printer on a sheet of a sheet size, and sheet size information specifying the sheet size corresponding to the setting value. The processor is configured to acquire, as a readjustment sheet size, a size of a sheet used for readjustment of the setting value upon receiving an instruction to perform the readjustment, and update the setting value stored in the memory based on a difference between the sheet size indicated by the sheet size information and the readjustment sheet size.

An image reading device includes an image reader movable along an image reading face, a casing to house the image reader, including a restraint holder, and a restraint to be held by the restraint holder of the casing and configured to restrict movement of the image reader. The restraint includes an operation portion to be disposed outside the casing. The operation portion is operated to move the restraint, in the restraint holder, to: a restricting position to restrict movement of the image reader; a first unlock position to cancel restriction of movement of the image reader; and a second unlock position at which movement of the image reader is not restricted. At the first unlock position, movement of the restraint to the restricting position is allowed. From the second unlock position, movement to the restricting position is less smooth than movement from the first unlock position to the restricting position.

An image inspection device includes a processor coupled to a sensor. The processor reads, using the sensor, an image formed on a recording material by an image forming device and creates a read image; causes an analysis to detect an abnormality in the read image and creates an analysis result; and creates a normal image file including the read image in which the abnormality has not been detected based on the analysis result.

An image forming apparatus according to an embodiment includes a communication interface for receiving image forming instruction information via a plurality of communication protocols. The image forming instruction information includes image data, and transmission information indicating the communication protocol used. An image forming section prints an image using one of a decolorable toner and a non-decolorable toner. A storage device stores correspondence information indicating, for each communication protocol, one of the decolorable toner and the non-decolorable toner for forming an image. A processor is programmed to determine the communication protocol with which the received image forming instruction information was transmitted. The processor determines, based on the correspondence information, one of the decolorable toner and the non-decolorable toner for forming an image, and controls the image forming section to print an image using the determined one of the decolorable toner and the non-decolorable toner.

An image forming apparatus includes a paper reading section, a similarity judgment section, and a control section. Between a downstream side in a paper conveyance direction of the paper feed section and a position where image formation is performed, the paper reading section reads an existing image already formed on a surface opposite to a formation surface of a new image newly formed on paper by an image formation section. Based on image data of the new image and image data of the existing image obtained by the image formation section, the similarity judgment section judges similarity between the both images. The control section, upon judging that the similarity is high, causes a pattern image to be formed on a surface of the paper where the existing image is formed, and upon judging that the similarity is not high, does not cause the pattern image to be formed.
