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.

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.
