Abstract
An image forming apparatus includes a photosensitive drum, a plurality of toner cartridges, a rotary, a main body, a driving device, a reading portion, and a controller. In a case where a state of request information is a first state, the controller takes a preparation state, in which an image forming operation is executable, after a reading operation is executed. In a case where the state of request information is a second state, the controller takes the preparation state without executing the reading operation.
Claims18
An image forming apparatus configured to execute an image forming operation for forming an image on a recording material, the image forming apparatus comprising:
- a photosensitive drum;
- a plurality of toner cartridges each including a cartridge storing portion in which cartridge information is stored;
- a rotary to which the plurality of toner cartridges are detachably mounted, the rotary being rotatable and including a plurality of developing devices each including a developing roller and configured to accommodate toner supplied from corresponding one of the plurality of toner cartridges;
- a main body accommodating the rotary and provided with an opening, the main body including a main body storing portion which is a non-volatile memory and is configured to store request information;
- a driving device including at least one driving source, the driving device being configured to move each of the plurality of toner cartridges from an inside to an outside of the main body through the opening and configured to rotate the rotary so that the rotary takes an exchange position and a reading position, wherein movement of either one of the plurality of toner cartridges to the outside of the main body is permitted when the rotary is in the exchange position, and a reading operation of the cartridge storing portion of either one of the plurality of toner cartridges is permitted when the rotary is in the reading position;
- a reading portion;
- and
- a controller configured to control the driving device and configured to perform the reading operation through the reading portion, the controller determining whether or not the reading operation is executed on the basis of the request information,
- wherein in a case where a state of the request information is a first state, the controller takes a preparation state, in which the image forming operation is executable, after the reading operation is executed, and
- wherein in a case where the state of the request information is a second state, the controller takes the preparation state without executing the reading operation.

- a reading portion;
- and
- a controller configured to control the driving device and configured to perform the reading operation through the reading portion, the controller determining whether or not the reading operation is executed on the basis of the request information,
- wherein in a case where a power source of the image forming apparatus is turned off and in a case where the power source of the image forming apparatus is turned on from a turned-off state, a state of the request information is held, and
- wherein in a case where the power source of the image forming apparatus is turned on from the turned-off state after the image forming operation is executed, the controller takes a preparation state, in which the image forming operation is executable, without executing the reading operation.
