摘要： The present invention provides a one-component development type developing apparatus including a rotatable electrostatic latent image holding member 1 on the surface of which an electrostatic latent image is formed, and using a toner 4 for rendering the electrostatic latent image visible, wherein when the shape factor SF-1 of a toner fine particle is expressed by: SF-1=(M2/A)×(π/4)×100 where A is the projected area of the fine particle and M is the absolute maximum length of the fine particle, then the shape factor SF-1 of the toner 4 is at least 100 and at most 140, and the developing apparatus includes: a toner holding member 3 that is formed from a silicone rubber elastic material and that is for holding the toner 4 and transporting it to the electrostatic latent image holding member 1; a toner layer regulating member 9 for forming the toner on the toner holding member 3 into a thin layer; and a toner supply member 5 that is formed from a silicone rubber foam and that rotates, in a position opposed to the toner holding member 3, in a direction opposite to that of the toner holding member 3, and an AC electric field is formed between the toner holding member 3 and the toner supply member 5.
