Abstract
An image forming apparatus has an image forming device for forming an image on a recording material in response to an image on a document. The apparatus also has a glossiness detection device for detecting from the document the level of glossiness of the document image. The image forming device is controlled based on an output from the glossiness detection device. With this construction, the level of glossiness in response to the document image can be reproduced on the recording material, thus improving the quality of reproduced images.
Claims23
An image forming apparatus comprising:
- image information obtaining means for obtaining information of an image on a document;
- image forming means for forming an image on a recording material in accordance with the information obtained by said image information obtaining means;
- glossiness detection means for detecting a level of glossiness of the image on the document;
- and
- control means for controlling said image forming means in accordance with the level of glossiness detected by said glossiness detection means;
- and
- wherein said image information obtaining means and said glossiness detection means scan the whole of the document substantially concurrently.
An image forming apparatus comprising:
- image forming means for forming an image on a recording material in accordance with an image on a document;
- glossiness detection means for detecting from the document a level of glossiness of the image on the document;
- input means for inputting recording materials of at least two different types, wherein said glossiness detection means generate one or more outputs based on the level of glossiness of the image on the document;
- and
- control means for controlling said image forming means, wherein said control means selects one of said types of recording material based on the output from said glossiness detection means.
An image forming apparatus comprising:
- image forming means for forming an image on a recording material in accordance with an image on a document;
- glossiness detection means for detecting from the document a level of glossiness of the image on the document;
- and
- a display unit for displaying the type of recording material which is determined from an output from said glossiness detection means.
An image forming apparatus comprising:
- unfixed-image forming means for forming an unfixed image on a recording material;
- fixing means for fixing the unfixed image onto the recording material by conveying the recording material;
- selecting means for selecting a mode from a plurality of modes among which is (i) a first mode for forming a glossy image at first on a first side of the recording material and then forming a glossy image on a second side of the recording material, which is the back side of the first side of the recording material, and (ii) a second mode for forming an image, of which the level of glossiness is lower than the level of glossiness of the image formed in the first mode, on both sides of the recording material;
- and
- controlling means for controlling said fixing means such that, when the first mode is selected, a conveying speed of said fixing means is higher when the unfixed image is on the first side of the recording material than when the unfixed image is on the second side of the recording material.
