摘要： An image forming apparatus includes a forming portion, an adjusting portion and a control portion. The forming portion is configured to form an image, while the adjusting portion is configured to execute an adjustment for correcting a pre-selected adjustable image forming condition based on a measurement of an image formed by the forming portion. The control portion is configured to control execution of the adjustment achieved by the adjusting portion. Specifically, the control portion obtains a plurality of kinds of variation values, which individually indicate a different state variation capable of involving a state change in the pre-selected adjustable image forming condition. The control portion calculates a complex evaluation of the current state of the pre-selected adjustable image forming condition based on the plurality of kinds of variation values, and determines a starting time for execution of the adjustment based on the complex evaluation.

摘要： An image forming apparatus for which a first mode using toners of plural colors including a black toner and a second mode using only the black toner can be set, includes a first printing cumulatively counting part that cumulatively counts a first number of pages for which image forming has been executed by using the toners of plural colors; a first printing determining part that determines whether the first number of pages counted by the first printing cumulatively counting part has exceeded a threshold; and a correction control part that controls not to execute a correcting process for image forming that uses the toners of plural colors but to execute a correcting process for image forming that uses only the black toner, when the second mode has been set in a case where the first printing determining part has determined that the first number of pages has exceeded the threshold.
