Abstract
A cooling device includes a cooling member to absorb heat from a conveyed sheet and a plurality of cooling units to cool the cooling member. Each of the cooling units includes a coolant channel through which a coolant flows and a liquid-cooling device configured to cool the coolant that flows in the coolant channel. The coolant channels are disposed on or inside the cooling member and arranged side by side in a sheet conveyance direction. The coolant channels includes a downstream coolant channel being downstream from at least one of the plurality of coolant channels in the sheet conveyance direction, and an upstream coolant channel being upstream from the downstream coolant channel in the sheet conveyance direction. One of the liquid-cooling devices coupled to the downstream coolant channel has a cooling capacity higher than a cooling capacity of another of the liquid-cooling devices coupled to the upstream coolant channel.
