Abstract
A developer replenishing apparatus including a developer container having a discharge port for discharging a developer therethrough, a screw for carrying the developer to the discharge port, a drive source for driving the screw, a motive power transmitting device for transmitting motive power from the drive source to the screw, and a rotation amount detecting device for detecting the amount of rotation of a predetermined rotary shaft in the motive power transmitting device, wherein the rotation period of the screw is an integral multiple of the rotation period of the predetermined rotary shaft.
Claims11
A developer replenishing apparatus comprising:
- a developer container having a discharge port for discharging a developer therethrough;
- a screw for carrying the developer to the discharge port;
- a drive source for driving said screw;
- motive power transmitting means for transmitting motive power from said drive source to said screw;
- and
- rotation amount detecting means for detecting an amount of rotation of a predetermined rotary shaft in said motive power transmitting means,
- wherein a rotation period of said screw is an integral multiple of a rotation period of said predetermined rotary shaft.
An image forming apparatus comprising:
- an image bearing member;
- developing means for developing a latent image formed on said image bearing member;
- a container for containing a developer to be supplied to said developing means;
- a screw for carrying the developer to a discharge port of said container;
- a drive source for driving said screw;
- motive power transmitting means for transmitting motive power from said drive source to said screw;
- and
- rotation amount detecting means for detecting an amount of rotation of a predetermined rotary shaft in said motive power transmitting means,
- wherein a rotation period of said screw is an integral multiple of a rotation period of said predetermined rotary shaft.
