A toner scraper includes a rubber member which is to be contacted with the rotation body of a developing device, and a plate spring member for elastically supporting the rubber member which is fixed to the front end portion of the plate spring member, wherein at least an edge portion of the rubber member which is in the side of a portion of the plate spring member at which the plate spring member is supported is contacted with the surface of the rotation body. Such a toner scraper which is contacted with a roll or belt-like rotation body disposed as a component of a developing device and which scrapes off a toner adhering to the surface of the rotation body is configured so that the scraper can scrape off the toner uniformly and stably even when the contact pressure is relatively low, the scraper can be produced at a low cost, and the scraper has a simple structure.
