摘要： There are provided an image reader with high resolution capability for images in a high density range and an image forming apparatus. An image reader 2 comprises a reflected light reading unit (11, 12, 13, 14, 10) for irradiating a surface to be read of an original sheet with a light and reading the amount of the reflected light and a transmitted light reading unit (15, 12, 13, 14, 10) for irradiating the original sheet with a light and reading the amount of the transmitted light, and calculates the density of an image of the original sheet based on the amount of the reflected light read by the reflected light reading unit and the amount of the transmitted light read by the transmitted light reading unit.

摘要： An image forming apparatus having an image carrier; an electrostatic latent image forming device that forms an electrostatic latent image on the image carrier; a development device having a housing section that stores toner therein, a stirring device for stirring the toner inside the housing section, and a toner, carrier that develops the electrostatic latent image into a toner image by imparting the toner to the image carrier; a voltage applying device that applies a development bias voltage between the image carrier and the toner carrier; a control device that makes the electrostatic latent image forming device and the development device form a test toner image on the image carrier; and a sensing device that senses a toner adhering amount of the test toner image. The control device determines whether to make the stirring device stir the toner based upon a relation between the toner adhering amount of the test toner image and the development bias voltage that was applied by the voltage applying device for formation of the test toner image.
