• wherein said film member is shifted to close said supply opening by a shifting force of said slide member in a supply opening closing direction.

A developer replenishing cartridge mountable on a developer receiving apparatus having a developer passing opening and a lid member for opening and closing said opening, comprising;

• a container for containing developer and having a developer supply opening;
• a flexible film member for sealing said supply opening, said film member being peelably adhered to said container and having a first film portion contacting with developer in said container and a second film portion folded back in a direction that said film member is pulled to open said supply opening;
• and
• a slide lid member engaged by said film member and shiftable together with said film member, said slide lid member having integrally therewith a first plate-shaped portion positioned between said first film portion and said second film portion when said supply opening is closed, and a second plate-shaped portion positioned between said second film portion and said lid member when said developer passing opening and said supply opening are closed, wherein a passage for said film member is defined between said first and second plate-shaped portions of said slide lid member;
• wherein said slide lid member is opposed to said lid member of said developer receiving apparatus both when said lid member closes said developer passing opening and said slide lid member closes said supply opening and when said lid member opens said developer passing opening and said slide lid member opens said supply opening,
• and wherein said first film portion of said film member enters into the passage between said first and second plate-shaped portions of said slide lid member when said supply opening is opened.

A developer replenishing cartridge mountable on a developer receiving apparatus having a developer passing opening and a lid member shiftable in a first direction to open the developer passing opening and in a second direction to close said developer passing opening, comprising:

• a container for containing developer and having a developer supply opening;
• a flexible film member, said film member having a first film portion peelably adhered to said container to seal said supply opening, and a second film portion folded back in a direction in which the film member is pulled, so that said first film portion is peeled from said container;
• and
• a manually operable gripper member fixed to a leading end portion of said second film portion and adapted to pull said film member, said gripper member being detachably connected to said container and having an engagement portion engagable with a predetermined portion of said lid member of the developer receiving apparatus;
• wherein said engagement portion of said gripper member is engaged with said predetermined portion of said lid member just before a time when a shifting movement of said lid member in said first direction is completed, and then said gripper member is separated from said container by said shifting force of said lid member in said first direction.

A developer replenishing cartridge mountable on a developer receiving apparatus having a developer passing opening and a hopper lid member shiftable in a first direction to open said developer passing opening and in a second direction opposite the first direction to close said developer passing opening, comprising:

• a container for containing developer and having a developer supply opening;
• a flexible film member for sealing said supply opening, said film member being peelably adhered to said container, said film member being pulled, after said hopper lid member opens said developer passing opening, to be peeled off from said container to open said supply opening;
• and
• a slide lid member engaged with said film member, said slide lid member being shifted in a direction to open said supply opening by a shifting force of said film member when said film member is pulled to be peeled off from said container, said slide lid member having an engagement portion capable of receiving a shifting force of said hopper lid member by engaging said hopper lid member when said hopper lid member is shifted in said second direction to close said developer passing opening, said slide lid member being shifted in a direction to close said supply opening by the shifting force of said hopper lid member, said slide lid member having integrally therewith first and second lid portions opposed to each other to define a film passage therebetween in which said film member is passed;
• wherein said film member is shifted to close said supply opening by a shifting force of said slide lid member in a supply opening closing direction.

A developer replenishing cartridge mountable on a developer receiving apparatus having a developer passing opening and a hopper lid member shiftable in a first direction to open said developer passing opening and in a second direction opposite the first direction to close said developer passing opening, comprising:

• a container for containing developer and having a developer supply opening;
• a flexible film member, said film member having a first film portion peelably adhered to said container to seal said supply opening and a second film portion folded back in a direction to pull the film member so that said first film portion is peeled off from said container, said first film portion contacting the developer in said container before said supply opening is opened;
• a manually operable gripper member fixed to a leading end portion of said second film portion and adapted to pull said film member, said gripper member being detachably connected to said container and having an engagement portion engagable with a predetermined portion of said lid member of the developer receiving apparatus, said engagement portion of said gripper member being engaged with said predetermined portion of said lid member, just before a time when a shifting movement of said hopper lid member in said first direction is completed, so that said gripper member is separated from said container by said shifting force of said lid member in said first direction, said gripper member separated from said container being manually pulled to peel said first film portion from said container;
• and
• a slide lid member engaged with said film member, said slide lid member being maintained in stationary condition at a position to close said supply opening while said hopper lid member of the developer receiving apparatus is in a shifting movement in said first direction to open said developer passing opening;
• wherein said slide lid member is shifted in a direction corresponding to said first direction to open said supply opening by a shifting force of said film member engaged therewith when said film member is pulled by said gripper member to be peeled off from said container,
• wherein said slide lid member has an engagement portion capable of receiving a shifting force of said hopper lid member by engaging said hopper lid member when said hopper lid member is shifted in said second direction to close said developer passing opening, and said slide lid member being shifted in a direction corresponding to said second direction to close said supply opening by the shifting force of said hopper lid member,
• wherein said slide lid member has integrally therewith first and second plate-shaped lid portions opposed to each other to define a film passage therebetween in which said film member is passed, said first film portion entering into said film passage when said film member is pulled by said gripper member, and
• wherein said film member is shifted to close said supply opening by a shifting force of said slide lid member engaged therewith in said direction corresponding to said second direction.
