摘要： An image forming apparatus includes: a skew correcting unit; a toner consumption amount calculating unit; and a memory assigning unit. The skew correcting unit corrects skew by controlling writing/reading of image data for a plurality of lines into/from a memory based on a skew correction amount that has been calculated previously. The toner consumption amount calculating unit refers to pixels on a plurality of peripheral lines among pixels of the image data stored in the memory when a toner consumption amount of a pixel to which toner adheres is calculated. The memory assigning unit assigns a capacity not used for skew correction on the memory that is mounted for the skew correcting unit to the toner consumption amount calculating unit.

摘要： A correction pattern (23) and a second pattern (50) are formed on an endless conveyor belt (5). The second correction pattern (50) is formed on the belt (5) before the correction pattern (23) is formed on the conveyor belt (5). A sensor (17,18,19) detects positional information of the correction pattern (23). A timer is started for detection of the correction pattern (23) from a time point at which the sensor detects the second pattern (50).
