ABSTRACT:
An image forming apparatus has a sheet feeding section for conveying a sheet for image formation, a stepping motor for driving the sheet feeding section, and a controller for controlling operation of the stepping motor. The controller includes a current value setting section. The current value setting section sets a current value that actuates the stepping motor based on sheet information obtained through at least one section selected from a thickness detecting section, size detecting section, and paper quality detecting section. The thickness detecting section detects a thickness of the sheet. The size detecting section detects a size of the sheet. The paper quality detecting section detects a paper quality of the sheet.
