An image forming apparatus capable of forming an image without transfer deviation or rumples by detecting the loop amount of the sheet material with a plurality of thresholds at multiple stages through a loop amount detecting portion detecting the loop amount of a sheet passing between conveyance guide members. The loop amount finely detected at the multiple stages through the loop amount detecting portion is reflected in a control and drive system, and, as a result, the sheet material can be conveyed while keeping the loop of the sheet material passing between the conveyance guide members at an appropriate amount.
