ABSTRACT:
A developing apparatus is for developing a latent image formed on an image bearing member. The apparatus includes: a developer accommodating portion for accommodating the developer; a developing device for developing the latent image; a light transmitting portion, provided in the developer accommodating portion, for transmitting light for detecting a remaining amount of the developer; a first developer feeding member, provided in the developer accommodating portion, for feeding the developer toward the developing means by rotation thereof; and a second developer feeding member for feeding the developer onto a light transmission surface of the light transmitting portion after the first developer feeding member rubs the light transmission surface by a free end with respect to a radial direction of the rotation. The second developer feeding member is provided on a rotation shaft which is also a rotation shaft of the first developer feeding member. The second developer feeding member does not rub the light transmission surface when the second developer feeding member rotates.
