Patent ID: 7072594

Claim:
A developing apparatus for developing a latent image formed on an image bearing member, said apparatus comprising: a developer accommodating portion configured to accommodate a developer; a developing device configured and positioned to develop the latent image; a light transmitting portion, provided in said developer accommodating portion, configured and positioned to transmit light for detecting a remaining amount of the developer; a first developer feeding member, provided in said developer accommodating portion, configured and positioned to feed the developer toward said developing device by rotation thereof; and a second developer feeding member configured and positioned to feed the developer onto a light transmission surface of said light transmitting portion after said first developer feeding member rubs the light transmission surface by a free end thereof with respect to a radial direction of the rotation, said second developer feeding member being provided on a rotation shaft which is also a rotation shaft of said first developer feeding member, wherein second developer feeding member does not rub said light transmission surface when said second developer feeding member rotates, wherein said second developer feeding member is flexible and is effective to scoop up the developer while rubbing an inner surface of said developer accommodating portion at a position which is below a horizontal plane passing through a center of rotation of the rotation shaft and which is in the same side as said developing device with respect to a vertical plane passing through the center of rotation of the rotation shaft.
