Abstract
A cleaning device includes a scraping portion whose edge is pressed against a rotational body to which toner adheres and that scrapes the toner off the rotational body, and a container that contains the toner that has been scraped off the rotational body. The container has a through-hole that opens in a portion of the container facing the scraping portion and that allows a gas to flow from an inside of the container toward the scraping portion.
Claims15
A cleaning device comprising:
- a scraping portion whose edge is pressed against a rotational body to which toner adheres and that scrapes the toner off the rotational body;
- and
- a container that contains the toner that has been scraped off the rotational body,
- wherein the container has a through-hole that opens in a portion of the container facing the scraping portion and that allows a gas to flow from an inside of the container toward the scraping portion,
- wherein the scraping portion includes
- a first scraping member whose edge is pressed against the rotational body and that scrapes the toner off the rotational body, and
- a second scraping member that is disposed on a downstream side of the first scraping member in a rotation direction of the rotational body, whose edge is pressed against the rotational body, and that scrapes the toner off the rotational body, and
- wherein the through-hole allows the gas to flow toward the second scraping member.
