Abstract
A one-component developing apparatus includes a developer carrier disposed in opposition to an electrostatic latent image receiving member, and a toner amount restricting member pressed so as to be in contact with the developer carrier. Wherein the toner amount restricting member includes a support member nade of a plate spring having tensile strength not smaller than 15 kgf/mm.sup.2 and yield strength not smaller than 10 kgf/mm.sup.2, and a soft elastic member disposed on the support member at a portion thereof to be pressed into contact with the developer carrier, the soft elastic member being attached on the support member so as to project from a forward end of the support member, whereby a thin layer of developer is formed on the developer carrier by the toner amount restricting member and charged so that the thin layer of toner is made adhere on an electrostatic latent image to make the electrostatic latent image visible.
