Abstract: An image forming apparatus includes an image forming portion, an exposure device, an image density sensor, and a control portion. The control portion can, by adjusting the development voltage based on the image density of a reference image and the amount of exposure from the exposure device, perform image density correction to adjust the image density. The control portion predicts the toner charge amount based on a formation condition of the reference image and the image density of the reference image and determines the timing of performing the image density correction next time based on the rate of change of the toner charge amount calculated using a first toner charge amount predicted when the image density correction was performed last time, a second toner charge amount predicted when the image density correction is performed this time, and the interval between the image density correction performed last time and this time.

Abstract: The mode setting unit sets the mode of the display unit to a blind mode. An operation for the mode setting unit to set the mode of the display unit to the blind mode is input to the input unit. The image changing unit changes the mode of the display unit from the normal mode to the blind mode based on the operation input to the input unit, and changes at least one of the color and density of the display image of the display unit according to the blind mode. When an operation for setting the mode of the display unit to the blind mode is input to the input unit, the display unit displays a preview image obtained by changing the image data before the image forming unit forms on the sheet in accordance with the blind mode as the display image of the display screen.
