Abstract: An image forming apparatus includes the following. An image forming unit forms an image. An image magnification changing unit changes a rotating speed of a polygon motor to change magnification of the image. A reference position detecting unit detects a reference position of a predetermined target component in a vertical scanning direction. A target component position calculating unit calculates a position of the target component based on a detecting result and a signal of a predetermined cycle according to the rotating speed of the polygon motor. A storage unit stores a correction table to correct density unevenness. An image data correcting unit obtains correction data based on the position of the target component and corrects the image data. A parameter correcting unit corrects a parameter according to a timing that the rotating speed of the polygon motor is changed.

Abstract: A color image forming apparatus includes a controller implemented using one or more hardware processors, wherein the controller: detects a line area; detects a background area adjacent to the line area; detects first one or more ink colors of first one or more inks to be used in the line area; detects second one or more ink colors of second one or more inks to be used in the background area; compares the first one or more ink colors and the second one or more ink colors to identify a combination pattern of the first one or more ink colors and the second one or more ink colors; and determines whether to correct amounts of the first one or more inks and amounts of the second one or more inks, based on the identified combination pattern.
