Abstract
An image forming apparatus includes an image bearing member, a development cartridge configured to store developer and including a developer bearing member bearing and conveying the stored developer to a position where an electrostatic latent image formed on the image bearing member is developed, a detection unit configured to detect a developer amount within the development cartridge, and a display portion configured to display information indicating that the developer within the development cartridge is insufficient to form an image per size of a recording member, based on a remaining developer amount within the development cartridge detected by the detection unit.
Claims18
An image forming apparatus configured to form a toner image on a recording member, comprising:
- an image bearing member;
- a development cartridge configured to accommodate developer and comprising a developer bearing member bearing and conveying the accommodated developer to a position where an electrostatic latent image formed on the image bearing member is developed;
- a detection unit configured to detect an amount of the developer accommodated in the development cartridge;
- and
- a display portion configured to, in a case in which the amount of the developer accommodated in the development cartridge detected by the detection unit is insufficient with respect to an amount of the developer for forming the toner image on a recording member of a first size, and is not insufficient with respect to an amount of the developer for forming the toner image on a recording member of a second size smaller than the first size, i) display information indicating that the amount of the developer accommodated in the development cartridge is insufficient to form the toner image on the recording member of the first size, and ii) display information indicating that the amount of the developer accommodated in the development cartridge is not insufficient to form the toner image on the recording member of the second size.
An image forming apparatus configured to communicate with an external device and to form a toner image on a recording member, comprising:
- an image bearing member;
- a development cartridge configured to accommodate developer and comprising a developer bearing member bearing and conveying the accommodated developer toward a position where an electrostatic latent image formed on the image bearing member is developed;
- a detection unit configured to detect an amount of the developer accommodated in the development cartridge;
- and
- a transmission portion configured to, in a case in which the amount of the developer accommodated in the development cartridge detected by the detection unit is insufficient with respect to an amount of the developer for forming the toner image on a recording member of a first size, and is not insufficient with respect to an amount of the developer for forming the toner image on a recording member of a second size smaller than the first size, i) transmit information indicating that the amount of the developer accommodated in the development cartridge is insufficient to form the toner image on the recording member of the first size to the external device, and ii) transmit information indicating that the amount of the developer accommodated in the development cartridge is not insufficient to form the toner image on the recording member of the second size to the external device.
An image forming apparatus configured to form a toner image on a recording member, comprising:
- an image bearing member;
- a development cartridge configured to accommodate developer and comprising a developer bearing member bearing and conveying the accommodated developer to a position where an electrostatic latent image formed on the image bearing member is developed;
- a detection unit configured to detect an amount of the developer accommodated in the development cartridge;
- and
- a display portion configured to, in a case in which the amount of the developer accommodated in the development cartridge detected by the detection unit is insufficient with respect to an amount of the developer for forming the toner image on a recording member of a first size, and is not insufficient with respect to an amount of the developer for forming the toner image on a recording member of a second size smaller than the first size, i) display information indicating that it is necessary to replace the development cartridge for forming the toner image on the recording member of the first size, and ii) display information indicating that it is not necessary to replace the development cartridge for forming the toner image on the recording member of the second size.
