The present invention relates to a developing device, and an image forming apparatus using the same. The developing device includes a toner holding member that is rotatably installed opposite to an image holding member which holds a latent image and circularly moves, a supply member that has a rough surface capable of capturing toner, a toner supply portion that supplies new toner, and a restriction member that restricts an amount of toner used for development, wherein the toner supply portion connects an accommodation chamber to a developing chamber via a toner transport path, wherein a developing chamber side opening is located on a lower side of an accommodation chamber side opening of the toner transport path, and wherein a width size in a direction following a rotation direction of the supply member in the developing chamber side opening of the toner transport path is set to be smaller than an outer diameter of the supply member in a projection plane viewed from the supply member side.
