摘要:
An image forming apparatus includes reading means for reading the density of a test pattern corresponding to each of plural recording elements of a recording head, the recording elements being arranged in an array, and the test pattern being recorded by the recording elements. An eliminating means eliminates error information, recorded from an area outside a test pattern are, from density information obtained by the reading means when the density of a test pattern end portion corresponding to an end portion of the array of plural of recording elements is determined. A means is provided for uniforming the image densities in correspondence with the plurality of recording elements based on density information from which the error information is eliminated by the eliminating means.

An ink jet recording apparatus for performing recording by discharging ink onto a recording medium from a discharging port provided for a recording head comprises a first electrode and a second electrode arranged for attracting unwanted ink discharged from the discharging port, and a power source for applying voltages of opposite polarities to each other to the first electrode and second electrode. This makes it possible to efficiently remove unwanted droplets which are generated at the time of recording, so that more stable and reliable recording can be performed.

An image recording apparatus includes plural recording heads that eject ink to record an image. Different tone characteristics of the images recorded by the recording heads are corrected by individually correcting the image signal for each head to improve the overall image quality of the image provided by the plural recording heads. Non-uniform density of the image recorded by the recording heads can also be corrected before tone correction is effected.
摘要:
In one printing scan of a plurality of printing scans of a multi-scan system, in which an ink dominant on the surface of a printing medium is set, the printing percentage of the ink relatively low in the degree of glossiness is set to be higher than that of the ink relatively high in the degree of glossiness. Thereby, the ink relatively low in the degree of glossiness becomes dominant in an overall image, so that the degree of glossiness is stabilized at a low level, even if the bi-directional printing operation is carried out, or the printing duty varies. Thus, the glossy-banding hardly occurs.

A laminating apparatus includes a conveyor for conveying a laminating object, a dryer for drying the laminating object conveyed by the conveyor, and a laminate device for effecting laminate processing on the laminating object dried by the dryer. A controller controls a temperature of the dryer so that the temperature of the dryer is adjusted to a predetermined temperature T1 before the laminating object arrives at the dryer, and so that the temperature of the dryer is adjusted to a predetermined temperature T2 greater than the temperature T1 when the laminating object is being dried by the dryer.

The present invention provides an image forming apparatus comprising an image bearing means for bearing an image, a transfer material bearing member for bearing and conveying a transfer material, and a transfer member for transferring the image on the image bearing means onto the transfer material born by the transfer material bearing member, the transfer member being arranged to contact with a surface of the transfer material bearing member opposite to a surface on which the transfer material is born. The transfer member comprises a first layer contacting with the transfer material bearing member and a second layer not contacting with the transfer material bearing member, and the first layer has coefficient of kinetic friction smaller than that of the second layer.
