Abstract: An image processing device 20 acquires a plurality of captured images obtained by imaging a sample including a target cell at a plurality of different focal distances, sets an object region for detecting the target cell in at least two of the plurality of captured images, and performs determination about whether or not the target cell is included in the object region based on whether or not an image feature quantity based on change in image information in an image in-plane direction and a focal distance direction of an image in the object region in the plurality of captured images satisfies conditions defined for the target cell.

Abstract: An image forming system includes a feed section, a transport section, a toner-image forming section, a fixing section, a problem detecting section, and an additional feed section. The feed section feeds a sheet. The transport section transports the sheet fed from the feed section. The toner-image forming section forms a toner image onto the sheet transported by the transport section. The fixing section fixes the toner image formed by the toner-image forming section onto the sheet. The problem detecting section detects a problem in a sheet transport operation. The additional feed section feeds an additional sheet from the feed section toward the fixing section if the number of sheets stopped by the transport section in accordance with detection of the problem by the problem detecting section and subsequently transported toward the fixing section after the sheet transport operation is resumed is smaller than a predetermined number.

Abstract: A recording medium includes a surface in which an infrared absorptance is less than a threshold value; and plural dot images that records information by an arrangement pattern formed on the surface, in which the infrared absorptance is equal to or more than the threshold value, and a specular gloss to infrared rays is equal to or less than 22%.

Abstract: In this invention, even if a thick resin coated recording medium having large heat capacity is used, a high quality image with an excellent gloss feeling is obtained. A transfer fixing device is provided with a press conveying mechanism which includes at least one pair of pressing bodies for nipping and conveying an image bearing and conveying body and a recording medium, and contact-conveys the recording medium on the image bearing and conveying body in a region exceeding a nip region of the pair of pressing bodies, and a heat supply adjusting mechanism which includes a heating source for heating the recording medium contact-conveyed on the image bearing and conveying body by the press conveying mechanism from both obverse and reverse sides to melt an unfixed image and a thermoplastic resin layer, and makes adjustment to cause heat supplied to an image bearing surface side of the recording medium to be more than heat supplied to a non-image bearing surface side of the recording medium.
