Patent ID: 8172390

Claim:
An image forming device comprising: a first moisture amount derivation component that derives a pre-drying moisture amount, which is a moisture amount contained in a recording medium after a liquid for forming an image has been applied by a liquid application component that applies the liquid to the recording medium; a drying component that dries the recording medium after the liquid has been applied to the recording medium by the liquid application component, a drying strength representing a degree of intensity with which the recording medium is dried being controlled; a storage component that stores drying information, including information representing a pre-drying moisture amount previously derived by the first moisture amount derivation component, and a drying strength of the drying component at which a recording medium was dried when the previously derived pre-drying moisture amount was derived; and a control component that controls the drying strength of the drying component on the basis of the pre-drying moisture amount derived by the first moisture amount derivation component and the drying information stored by the storage component.
