PROBLEM TO BE SOLVED: To obtain information on surrounding temperature and humidity without loading temperature-humidity sensors, and to enable a process control correction or toner control correction.SOLUTION: An image formation device (100) comprises: a photoreceptor (3); an exposure device (1) that forms a latent image by exposing the photoreceptor; a developing unit (2) that develops the latent image by depositing toner to the latent image; and a control unit (150) that controls image formation by the photoreceptor and developing unit. The control unit comprises: a weather information acquisition unit (151) that acquires weather information on temperature humidity at a current point of time from a weather forecast of a district having the image formation device installed; a process control unit (153) that implements a correction control of a process control on the basis of the weather information thereon at the current point of time; and a toner control unit (154) that implements a correction control of a toner control on the basis of the weather information at the current point of time.SELECTED DRAWING: Figure 3 |
