Abstract: An image forming apparatus includes an image forming portion, a toner storage container, an odor generator, an odor sensor, and a control portion. The image forming portion includes an image carrying member and a development device that develops an electrostatic latent image formed on the image carrying member into a toner image. The toner storage container is rotatable, stores toner for forming the toner image, and is removably mountable in the image forming apparatus. The odor generator is provided at a position where it is rotatable together with the toner storage container, and carries an odor substance. The odor sensor senses the odor substance diffusing from the odor generator. The control portion rotates the toner storage container after its mounting in the image forming apparatus before toner supplying operation, and senses the odor substance at a sensing position where the odor generator is closest to the odor sensor.

Abstract: The control unit of an image forming apparatus applies, with a voltage application unit, a collection voltage to a cleaning roller when an image is formed, estimates a surface potential of an image carrying member based on a current flowing between the image carrying member and the cleaning roller which is detected by a current detection unit when the collection voltage is applied and changes the collection voltage and the rotation speed of the cleaning roller when the surface potential of the image carrying member is lowered.

Abstract: An image forming apparatus includes an image forming portion, a toner storage container, an odor generator, an odor sensor, and a control portion. The image forming portion includes an image carrying member and a development device that develops an electrostatic latent image formed on the image carrying member into a toner image, and forms the toner image based on image data. The toner storage container stores toner for forming the toner image, and is removably mountable in a main body of the image forming apparatus. The odor generator is provided on the toner storage container, and carries an odor substance. The odor sensor is provided in the main body of the image forming apparatus, and senses the odor substance diffusing from the odor generator. The control portion identifies the type of toner storage container based on the odor substance sensed by the odor sensor.
