Toner container having specific dimensions and image forming system

A toner container mountable to and demountable from an image forming apparatus, the toner container comprising:

• a bag member made of flexible film material, the bag member including (i) a side surface portion configured to form an accommodating space for accommodating toner inside thereof and extending in a first direction and (ii) a bottom portion configured to close the accommodating space from a first side in the first direction;
• and
• a discharging member connected to the bag member and configured to discharge the toner from the accommodating space to outside of the toner container, the discharging member including (i) an opposing surface configured to close the accommodating space from a second side of the bag member in the first direction and opposed to the bottom portion, a receiving opening provided in the opposing surface and configured to receive the toner inside the accommodating space, and (iii) a discharging opening communicating with the receiving opening and configured to discharge the toner received via the receiving opening,
• wherein, when directions perpendicular to the first direction and perpendicular to each other are defined as a second direction and a third direction, a length from the opposing surface to an end in an opposite side of the opposing surface of the bag member in the first direction is defined as Xmax, in a case in which a position X, where 0≤X≤Xmax, using the opposing surface as a reference in the first direction is given, a length of the bag member on a plane perpendicular to the first direction in the second direction is defined as Y and a length of the bag member on the plane in the third direction is defined as Z, and in a case in which Y and Z are YO and ZO in X=0, then:
