Abstract: A toner container includes a storage portion configured to store toner and a communicating member including a receiving port, a discharge port, and a passage. The passage includes a first inclined surface and a second inclined surface connecting the first inclined surface and the discharge port to each other. When viewed in a third direction perpendicularly intersecting with both of a first direction and a second direction, the first inclined surface is inclined with respect to the second direction such that a more downstream portion of the first inclined surface in the first direction is closer to the discharge port in the second direction, and the second inclined surface is inclined with respect to the second direction such that a more downstream portion of the second inclined surface in the first direction is closer to the discharge port in the second direction.

Abstract: A toner case includes a case main body, a feeding mechanism, a displacement member, and an elastic member. The case main body stores toner. A ventilation port is formed in the case main body. The feeding mechanism feeds the toner to outside the case main body. The displacement member includes a seal portion and is configured to be displaced between a closing position and an opening position. When the displacement member is at the closing position, the seal portion closes the ventilation port, and when the displacement member is at the opening position, the seal portion opens at least a part of the ventilation port. The elastic member holds the displacement member at the closing position by applying an elastic force to the displacement member.

Abstract: A printer prints an image on a sheet. A sensor measures a measurement image printed on the sheet. A controller control the printer to print a plurality of test images and a separator on the sheet. The separator is used to control a measurement timing of an external measurement device. The controller controls the sensor to measures the plurality of test images on the sheet, obtains measurement data related to the plurality of test images. The measurement data is outputted from the external measurement device. The controller generates a conversion condition based on a result of measuring the plurality of test images by the sensor and the obtained measurement data. The conversion condition is used to convert the result of measuring by the sensor into a measurement result of an external measurement device.

Abstract: An image forming apparatus includes an image forming portion configured to form an image on a recording media and including a developer bearing member configured to bear developer and carry the developer, a regulating portion disposed opposite to the developer bearing member and configured to regulate an amount of the developer on the developer bearing member, a first chamber configured to supply the developer to the developer bearing member, and a second chamber configured to communicate with the first chamber to form a circulating route of the developer. In addition, a first feeding member feeds the developer in the first chamber, and a second feeding member feeds the developer in the second chamber. A control portion executes, in a non-image forming state, a mode of driving the developer bearing member in a condition in which the first feeding member is stopped.

Abstract: A toner case includes a case main body, a rotator, a transmitter, a moving mechanism and a manipulation member. The rotator rotates around a rotation axis. At least a part of the rotator is stored in the case main body. The transmitter is arranged outside the case main body and transmits rotation to the rotator. The manipulation member is arranged outside the case main body. As the manipulation member moves from a first manipulating position to a second manipulating position, the moving mechanism moves the transmitter from a first position to a second position which is arranged at an outside of the first position in a rotation axis direction of the rotator. As the manipulation member moves from the second manipulating position to the first manipulating position, the moving mechanism moves the transmitter from the second position to the first position.
