An image forming apparatus includes an exposer including an organic electroluminescence element including at least an anode for injecting a hole, a luminescent layer having a luminescent region and a cathode for injecting an electron on a board. A photosensitive member is formed with an electrostatic latent image by exposing light of the exposer, a developer forms a toner image on the photosensitive member by supplying a toner to the electrostatic latent image, and a cooler cools the organic electroluminescence element such that the temperature of the organic electroluminescence element can be controlled.

In an electrophotography apparatus, a dark reference is derived from an output of a density sensor detecting a pattern of saturation density, and a highlight reference is derived from an output of the density sensor detecting a surface of an intermediate transfer sheet. Based on these dark reference and the highlight reference, read-in values of gradation correction patterns detected by the density sensor is normalized to make a gradation correction table.

An electronic pen transmits pen information to a controller corresponding to detection of a touch condition, and thereafter turns ON a connecting switch that disconnects electrical connection between the tip portion and the grip portion of the pen that are provided in a state of being electrically disconnected from each other so as to cause a pen input acceptance state. The controller determines that position detection information is from the electronic pen when the position detection information is received from a position detecting device after the pen information is received from the electronic pen, while the controller determines that position detection information is from a finger when the position detection information is received from the position detecting device without receiving the pen information from the electronic pen.

An image formation apparatus for conducting gradation recording by changing the size of dots on the basis of inputted image data, has a memory unit for storing a plurality of input image level-print output level characteristics for effecting gradation correction to the inputted image data, and a gradation correction unit for selecting different input image-print output level characteristics from the memory unit in each 1/n period of a transmission period of the inputted image data when n is a natural number of 2 or more, and determining the size of dots to be printed, in accordance with this output level. The apparatus can minimize the drop of resolution, can improve gradation, and can satisfy both gradation and resolution in good balance.
摘要:
An image formation apparatus for performing a gradation recording by changing a size of a dot on the basis of an image data inputted to the apparatus. The apparatus divides an image into a plurality of blocks each comprising a predetermined number of pixels and gives a preferential order with respect to a position within each of the plurality of divided blocks. When the preferential order is higher, the size of the corresponding dot is first enlarged on the basis of a density of the image data. This arrangement can prevent generation of a texture and deterioration of the image resolution irrespective of the case that characters or line drawings are mixed with half-tone pictures in the image.
