COOLING DEVICE, IMAGE FORMING APPARATUS, AND IMAGE FORMING SYSTEM

WIPO Patent Application WO/2019/235649

A1

A first belt 21 that is cooled by a heat sink has, on the upstream side of a cooling nip T4, a flat surface 21a for guiding a recording material S conveyed from a belt conveying device 70 to the cooling nip T4. The belt conveying device 70 is disposed such that an angle θ2 formed between a surface F parallel to a guide direction in which the recording material S is guided and the flat surface 21a becomes an acute angle, and guides the recording material S such that the leading end thereof hits against the flat surface 21a. The recording material S is brought into contact with the flat surface 21a over a predetermine range Y on the upstream side from an upstream end T4a of the cooling nip T4a, and the recording material S is guided to the cooling nip T4 while being cooled. In doing so, cooling of the recording material S is started before an entry into the cooling nip T4, thereby making it possible to suppress temperature increase of a second belt 25 due to heat of the recording material S, and consequently, toner, wax, and the like do not easily adhere to the second belt 25 from the recording material S.
