摘要： An image forming apparatus includes temperature sensors (12) that measure temperatures at different locations in the longitudinal direction of a photosensitive drum. The image forming apparatus also includes an image processing circuit (200) configured to change an exposure condition in the longitudinal direction of the photosensitive drum based on measured values obtained by the temperature sensors.

摘要： An image forming apparatus is provided in which on-surface potential unevenness of an image carrier can be suppressed, and with which an output image having excellent on-surface uniformity of color or the like can be obtained. The image forming apparatus includes: a photoconductive image carrier; charger which charges the image carrier; image exposing unit which exposes an image on a surface of the image carrier after the charging to form a latent electrostatic image; developing unit which develops the latent electrostatic image by adhering toner to the latent electrostatic image to form a toner image; and transfer charger which transfers the obtained toner image to a final supporting member such as plain paper.

摘要： The present invention provides: a color image forming method that forms an image using a deep toner and a pale toner at least for one color such that the pale toner is used to form an image in a high lightness area and the pale toner and the deep toner are used in combination to form the image in a half tone area; a toner kit having a deep toner and a pale toner which are separated from each other. According to the present invention, a high quality image can be formed while inhibiting graininess and roughness over a broad image area.

摘要： The present invention further improves gradation characteristics from a highlight region to a high-density region. First, the correction processing receives image data, and an image attribute discrimination discriminates whether the data are related to a character/thin line or others on the basis of attribute information on a pixel of interest. If it is discriminated that the data are related to a character/thin line, a pattern matching to data stored in a line buffer is performed to obtain a pixel distance, and in accordance with the pixel distance, a correction amount is determined on the basis of an LUT set in a correction amount determination. Subsequently, on the basis of the determined correction amount, corrected image data are generated and output to the following step.

摘要： The image forming apparatus includes an image forming unit capable of forming an image with a hypochromic toner and a hyperchromic toner of a substantially same hue, a first toner containing portion containing the hypochromic toner, a second toner containing portion containing the hyperchromic toner, and a density detecting unit which detects a density of an image formed with the hypochromic toner and the hyperchromic toner. Thus an image can be formed with the hypochromic toner and the hyperchromic toner of a substantially same hue.
