備えていることを特徴とする画像形成装置。 An image forming apparatus comprising: an image processing section that visualizes an electrostatic latent image formed on the surface of a photoreceptor using a developing device and then transfers the image to paper; and a paper supply section that supplies paper to the photoreceptor. In the paper feeding section, the paper feeding section includes two pre-transfer guide means spanning the entire width of the paper for advancing the paper at two types of angles, fast and fast, to the surface of the photoreceptor, and also includes a large thin ordinary paper sheet. Of the two pre-transfer guide means, a recessed step portion is formed on a part of the guide surface that guides the pre-transfer guide means on the steeper angle side to guide paper that is smaller and thicker than the normal paper to the pre-transfer guide means on the gentler angle side. An image forming apparatus characterized by comprising stepped guide means.
