Abstract

The invention discloses an image forming apparatus and a sheet guide unit. The image forming apparatus including a guide unit including: a length-adjusting assembly including a length-adjusting rack part, which is adjusted according to a length of printing medium; a width-adjusting assembly including a width-adjusting rack part, which is adjusted according to a width of printing medium; and a pinion assembly, which interlocks the width-adjusting assembly interlock with the length-adjusting assembly. The pinion assembly includes a first pinion part, which engages with the length-adjusting rack, and a second pinion part, which engages with the width-adjusting rack and rotates together with the first pinion part. The first pinion part and the second pinion part have a stepped shape.

Description

technical field [0001] Aspects of the present invention relate to an image forming apparatus. Background technique [0002] The image forming apparatus prints an image on a printing medium (for example, paper) according to an input image signal. As one type of image forming apparatus, an electrophotographic color image forming apparatus is configured to scan a light beam onto a photoreceptor charged with a predetermined potential, thereby forming an electrostatic latent image on the peripheral surface of the photoreceptor. The latent electrostatic image is developed into a visible image by supplying a developer to the latent electrostatic image, which is then transferred and fused to paper. [0003] The image forming apparatus is provided with a paper supply unit that supplies paper on which a visible image is to be formed. The paper feeding unit generally includes: a paper cassette, in which paper is loaded; and a pick-up roller, which picks up the paper loaded in the pap...
