摘要： An image forming apparatus includes a heating device, a recording medium ejector, a recording medium tray, an outer wall having an intake, and a filter. The heating device heats a recording medium having an image on one side of the recording medium. The recording medium ejector ejects the recording medium with the one side facing downward. On the recording medium tray, the recording medium ejected by the recording medium ejector is stacked. The intake is open toward the recording medium tray and is disposed at a position below the recording medium ejector. At the position, a maximum amount of recording media placeable on the recording medium tray does not cover at least a part of the intake. The filter collects foreign substances in air sucked from the intake.

摘要： A nip former that forms a nip between an endless belt and a pressure rotator includes a base that is made of aluminum and has a nip forming face disposed opposite the nip. An anodic oxidation coating is treated with sealing and coats at least the nip forming face. The anodic oxidation coating has a thickness that is not smaller than 22 μm and is not greater than 45 μm and a variation in thickness that is not greater than 20 percent. The base and the anodic oxidation coating define a nip forming portion that is disposed opposite the nip. The nip forming portion has a thickness that is not smaller than 0.40 mm and is not greater than 1.20 mm.

摘要： An image forming apparatus includes an exhaust duct to guide air inside the image forming apparatus to an outside of the image forming apparatus. A positive ion generator emits a positive ion into the exhaust duct. A negative ion generator emits a negative ion into the exhaust duct. The negative ion generator is shifted from the positive ion generator in one of an air flow direction of the air moving inside the exhaust duct and a direction perpendicular to the air flow direction.

摘要： An apparatus for producing a detachable information sheet includes an image forming device, an applying and curing unit, and a heating and pressing unit. The image forming device includes an image bearing body, an electrostatic latent image forming unit to form an electrostatic latent image on the image bearing body, a development unit to develop the latent image with a toner to form a visible toner image, a transfer unit to transfer the toner image from the image bearing body onto a recording medium, and a fixing unit to fix the toner image on the recording medium. The applying and curing unit applies an energy-ray curable composition precursor onto the recording medium having the toner image fixed thereon, and cures the precursor to form an energy-ray curable composition to coat the recording medium. The heating and pressing unit heats and presses the recording medium coated with the energy-ray curable composition.
