A scraping device comprising:
- a scraping part configured to contact a rotating contact part to scrape off attached matter attached to the contact part;
- a rotation part configured to rotate;
- and
- an applying part that is attached to the rotation part, is configured to rotate with the rotation part, and is configured to strike the scraping part to apply an impact to the scraping part,
- wherein the applying part is configured to rotate about a same axis as the rotation part, and a position where the applying part is attached to the rotation part is not changed in accordance with a rotation of the rotation part,
- wherein the rotation part is a transport part configured to transport the attached matter scraped off by the scraping part,
- wherein the transport part includes a shaft and a spiral blade formed on an outer circumference of the shaft,
- wherein the blade is configured to transport the attached matter as the shaft rotates, and
- wherein the applying part is attached to the shaft.
