Abstract

A base toner amount determining unit is configured to determine a base toner amount without taking edge effect into account, the base toner amount corresponding to a pixel value of image data for which gradation correction has not been performed. A laser profile applying unit is configured to perform for the base toner amount a first spatial filter process corresponding to a laser profile of an exposure device. An edge emphasis amount determining unit is configured to perform a second spatial filter process for the base toner amount before the first spatial filter process or after the first spatial filter process and thereby determine an edge emphasis amount correspond to the edge effect. A toner counter is configured to count as a toner consumption amount a sum of the base toner amount after the first spatial filter process and the edge emphasis amount.
