ABSTRACT:
An image forming apparatus includes an image forming mechanism and a control device. The image forming mechanism performs an image forming operation under predetermined image forming conditions, and includes an image carrying member for forming an electrostatic latent image thereon, a development device for developing the electrostatic latent image into a toner image, and a transfer device for transferring the toner image to a recording medium. The control device controls an amount of toner replenished to the development device, sets a developer mixing time for evenly mixing developer in the development device, causes the development device to mix the developer for the set developer mixing time, causes the image forming mechanism to form toner image patterns, detects the toner image patterns, and determines the predetermined image forming conditions based on the detection of the toner image patterns. An image forming method is also described.
