Toner case and image forming apparatus

A toner case comprising:

• a case main body storing a toner;
• and
• an agitator rotating around a rotation axis extending along one direction and agitating the toner stored in the case main body,
• wherein the case main body includes:
• a curve curved in an arc shape around the rotation axis;
• and
• a recess recessed from the curve toward a side remote from the rotation axis,
• wherein in a state where the agitator is in a first rotating position, a part of the agitator comes into contact with an inner circumferential face of the curve so that the part of the agitator is in a bent state, and in a state where the agitator is in a second rotating position, the part of the agitator is inserted into the recess,
• the toner case further comprising a gear arranged at an outside of the case main body in the one direction and rotating integrally with the agitator,
• wherein the gear includes a moving mark at a position to be visible from an exterior in the state where the agitator is in the second rotating position, the moving mark moving as the gear rotates.

A toner case comprising:

• a case main body storing a toner;
• and
• an agitator rotating around a rotation axis extending along one direction and agitating the toner stored in the case main body,
• wherein the case main body includes:
• a curve curved in an arc shape around the rotation axis;
• and
• a recess recessed from the curve toward a side remote from the rotation axis,
• wherein in a state where the agitator is in a first rotating position, a part of the agitator comes into contact with an inner circumferential face of the curve so that the part of the agitator is in a bent state, and in a state where the agitator is in a second rotating position, the part of the agitator is inserted into the recess,
• wherein the curve has a discharge port through which the toner is discharged from the case main body, and
• the agitator includes:
• a holding piece provided at an interval from the curve;
• and
• a film held by the holding piece,
• wherein in the state where the agitator is in the first rotating position, the film comes into contact with the inner circumferential face of the curve so that the film is in a bent state, and in the state where the agitator is in the second rotating position, the film is inserted into the recess.

A toner case comprising:

• and
• an agitator rotating around a rotation axis extending along one direction and agitating the toner stored in the case main body,
• wherein the case main body includes:
• a curve curved in an arc shape around the rotation axis;
• and
• a recess recessed from the curve toward a side remote from the rotation axis,
• wherein in a state where the agitator is in a first rotating position, a part of the agitator comes into contact with an inner circumferential face of the curve so that the part of the agitator is in a bent state, and in a state where the agitator is in a second rotating position, the part of the agitator is inserted into the recess,
• wherein the recess is curved in an arc shape, and
• a radius of curvature of the recess is smaller than a radius of curvature of the curve.
