Abstract
A toner supply container detachably mountable to a main assembly of an electrophotographic image forming apparatus includes (a) a toner accommodating portion for accommodating toner; (b) a toner supply opening or port for discharging toner accommodated in the toner accommodating portion; (c) a toner feeding member for feeding the toner accommodated in the toner accommodating portion toward the toner supply opening by rotation thereof, wherein a center of rotation of the toner feeding member is in an opening region of the toner supply port as seen in the longitudinal direction of the toner feeding member.
Claims26
A toner supply container detachably mountable to a main assembly of an electrophotographic image forming apparatus, comprising:
- (a) a toner accommodating portion for accommodating toner;
- (b) a toner supply opening or port for discharging toner accommodated in said toner accommodating portion;
- (c) a toner feeding member for feeding the toner accommodated in said toner accommodating portion toward said toner supply opening by rotation thereof, wherein a center of rotation of said toner feeding member is in an opening region of said toner supply port as seen in the longitudinal direction of said toner feeding member.
A toner supply container detachably mountable to a main assembly of an electrophotographic image forming apparatus, comprising:
- (a) a toner accommodating portion for accommodating toner;
- (b) a toner supply port for discharging the toner accommodated in said toner accommodating portion, wherein said toner supply port is projected outwardly from a lateral end surface crossing with the longitudinal direction of said toner accommodating portion;
- (c) a toner feeding member for feeding the toner accommodated in said toner accommodating portion toward said toner supply opening by rotation thereof, wherein a center of rotation of said toner feeding member is in an opening region of said toner supply port as seen in the longitudinal direction of said toner feeding member, and wherein said toner feeding member has a driving force receiving portion adjacent a toner supply port in the longitudinal direction, wherein said driving force receiving portion, when said toner supply container is detachably mounted to the main assembly of said apparatus, receives driving force from the main assembly of the apparatus, using said toner supply port.
A toner supply container detachably mountable to a main assembly of an electrophotographic image forming apparatus, comprising:
- (a) a toner accommodating portion for accommodating toner;
- (b) a toner supply port for discharging the toner accommodated in said toner accommodating portion, wherein said toner supply port is projected outwardly from a lateral end surface crossing with the longitudinal direction of said toner accommodating portion;
- (c) a toner feeding member for feeding the toner accommodated in said toner accommodating portion toward said toner supply opening by rotation thereof, wherein said toner feeding member includes a shaft portion and a helical feeding portion extended along a longitudinal direction of said shaft portion, wherein at least one full-turn of the helical portion is in said toner supply port, wherein the center of rotation of said toner feeding member is substantially concentric with the center of the opening region of said toner supply port as seen in the longitudinal direction of said toner feeding member;
- and said driving force receiving portion is extended from the shaft portion in its axial direction, wherein said toner feeding member has a driving force receiving portion adjacent a toner supply port in the longitudinal direction, wherein said driving force receiving portion is extended from said shaft portion in its axial direction to project out of said toner supply port, and wherein said driving force receiving portion, when said toner supply container is detachably mounted to the main assembly of said apparatus, receives driving force from the main assembly of the apparatus, using said toner supply port;
- wherein said toner supply container supplies, into the main assembly of said apparatus from said toner supply port, the toner accommodated in said toner accommodating portion by said toner feeding member in accordance with consumption of the toner in the main assembly of said apparatus, when said toner supply container is detachably mounted to the main assembly of said apparatus.
An electrophotographic image forming apparatus for forming an image on a recording material, comprising:
- (a) mounting means for detachably mounting a toner supply container, said toner supply container including:
- a toner accommodating portion for accommodating toner;
- a toner supply opening or port for discharging toner accommodated in said toner accommodating portion;
- a toner feeding member for feeding the toner accommodated in said toner accommodating portion toward said toner supply opening by rotation thereof, wherein a center of rotation of said toner feeding member is in an opening region of said toner supply port as seen in the longitudinal direction of said toner feeding member;
- (b) a toner receiving portion for receiving the toner fed through said toner supply port when said toner supply container is detachably mounted to the main assembly of said apparatus by said mounting means.
A toner supply container detachably mountable to a main assembly of an electrophotographic image forming apparatus, comprising:
- (a) a toner accommodating portion for accommodating toner;
- (b) a toner supply port for discharging the toner accommodated in said toner accommodating portion;
- (c) a toner feeding member for feeding the toner accommodated in said toner accommodating portion.
