Abstract: A method of forming an image includes forming, on a recording medium (P), a special-light responsive image (201) that includes an image forming material including a special-light responsive image forming material that reacts to special light other than visible light and a special-light irresponsive image (202) that includes an image forming material including the special-light responsive image forming material. The special-light responsive image forming material of the special-light irresponsive image (202) is less than the special-light responsive image forming material of the special-light responsive image (201), and the special-light irresponsive image (202) is a prevention image that prevents visibility of the special-light responsive image (201). The forming includes forming an overlaid portion (203) in which at least a portion of one of the prevention image and the special-light responsive image (201) is overlaid on top of another one of the prevention image and the special-light responsive image (201).

Abstract: [Summary] [Object] to provide a plant culturing apparatus and method which reduce the operating noise, allow liquid feeding and discharging as well as aeration within a culture vessel, thus facilitating culturing of a plant. [Solution] The plant culturing apparatus comprises: a transport unit 3 capable of transporting a fluid W between a culture vessel P for culturing a plant G and a reservoir T capable of reserving therein the fluid W to be fed to the plant G through a feed/discharge tube 2 connected and communicated with the transport unit 3 via a tube pump 1; and a direction switching unit 6 capable of switching a transporting direction of the fluid W by the transporting unit 3 between a direction for feeding the fluid W from the reservoir T to the culture vessel P and the opposite direction for discharging the fluid W from the culture vessel P to the reservoir T.
