Claims

[Scope of utility model registration request]

In a slit exposure type image forming apparatus that uses a bar-shaped exposure light source to visually confirm the image forming area of the original by light that passes through the original, a document confirmation mode is set to a mode for checking the image forming area of the original. a setting means, a light amount setting means for setting the light amount of the exposure light source, a lighting control means for controlling the light amount of the exposure light source based on information from the above two setting means, and a lighting control means for controlling the light amount of the exposure light source under the control of the lighting control means. What is claimed is: 1. A document position confirmation device for an image forming apparatus, comprising: a lighting means for lighting up a document position confirmation device for an image forming apparatus;
