Droplet drying device and image forming apparatus

There is provided a droplet drying device (14) including: a light source (B) that irradiates, with light, and dries a droplet ejected to a recording medium (P) by a forming unit (26) that ejects the droplet to form an image; a reading unit (16) that reads a specifying image in which a light emitting condition of the light source (B) is specified and which is formed by the forming unit (26) in a region out of an image forming region on the recording medium (P); and a light source controller (18) that controls the light source (B) such that the light source (B) emits light in accordance with the light emitting condition specified in the specifying image read by the reading unit (26) so as to irradiate the droplet with the light. z r-1 12M 12 12Y 14 X 12K K MY 9J18 z F 2'''B / V 8 8 8 8 8 8 80 8 8 8 0 8 8 8 8 0 O O O O O O O 8 8 8 0 8 8 8 8 8 8 8 8 8 0 8 8 0 i 0 ') ') ')0 B1 B' B3 B4 B5 B6 E0 B8
