Image forming apparatus
An image forming apparatus includes: a conveying device that conveys a recording medium; a droplets ejecting device that ejects droplets onto the recording medium being conveyed by the conveying device; a drying unit that dries the droplets that have been ejected on the recording medium being conveyed by the conveying device; and a varying unit that varies a conveyance path length from the droplets ejecting device to the drying unit in accordance with at least one of a conveyance speed of the recording medium and an ejected droplets permeation characteristic of the recording medium.
1. An image forming apparatus comprising:
a conveying device that conveys a recording medium in a conveyance direction;
a droplets ejecting device that ejects droplets onto the recording medium being conveyed by the conveying device;
a drying unit that dries the droplets that have been ejected on the recording medium being conveyed by the conveying device, the drying unit comprising a plurality of infrared heaters arranged in the conveyance direction; and
a varying unit that varies a conveyance path length from the droplets ejecting device to the drying unit in accordance with at least one of a conveyance speed of the recording medium and an ejected droplets permeation characteristic of the recording medium,
wherein the varying unit varies the conveyance path length by varying a drying start position, on an upstream side in the conveyance direction, in a drying area of the drying unit by selecting at least one of the plurality of infrared heaters to be turned on.
