Droplet drying device and image forming apparatus

An image forming apparatus comprising:

• an ejection unit that ejects droplets on a recording medium to form an image on the recording medium;
• and
• a droplet drying device disposed downstream of the ejection unit in a conveying direction in which the recording medium is conveyed,
• wherein the droplet drying device comprises:
• a plurality of light emitting devices arranged in a two-dimensional manner to irradiate the droplets with light to dry the droplets;
• a regular irradiation capability portion provided in a region corresponding to an image forming region of the recording medium where the image is formed, the regular irradiation capability portion having a predetermined light irradiation capability;
• and
• a low irradiation capability portion provided in a region corresponding to a region of the recording medium set to have a lower image-forming density than the image forming region, a light irradiation capability of the low irradiation capability portion being lower than the predetermined light irradiation capability,
• the image forming region being a region in which an actual image of an original document is formed, and the lower image-forming density region being a region distinct from the image forming region and being a margin on both sides of the recording medium in a sheet conveying direction.
