An image forming apparatus including an image forming unit for forming an image on a recording sheet including a special sheet, and a controller for allowing the image forming unit to carry out an image forming sequence which forms an image on the recording sheet, wherein the controller allows the image forming unit to control a cleaning operation of the image forming unit in response to image formation on the special sheet by the image forming unit.
摘要:
There is provided an image forming apparatus which is capable of operating in a stable condition and in an efficient manner by omitting automatic adjustment in the case where there is no necessity of carrying out the automatic adjustment when the image forming apparatus returns from a power-saving mode to a normal mode. A CPU shifts the operation mode of the image forming apparatus to a power-saving mode in which power consumption is saved. The CPU detects at least one of a status of the image forming apparatus before the operation mode is shifted to the power-saving mode and a status of the image forming apparatus in the power-saving mode. The CPU determines the contents of a return process executed when the operation mode returns to a normal mode from the power-saving mode, according to the detected status of the image forming apparatus.

There is provided an image forming apparatus which is capable of securing a time period for measuring the base reflected light quantity required for the base correction, and at the same time, reducing a time period required for the entire image density control. An image forming unit includes an image carrier disposed to be exposed to light to have a latent image formed thereon, an electrostatic charger that charges the image carrier to a predetermined polarity, a developing device that visualizes the latent image formed on the image carrier to form a visible image, and an endless belt onto which the visible image is transferred. A CPU controls the image forming unit to form predetermined detection patterns on the endless belt. The detection patterns and the quantity of reflection light from the endless belt are detected. The CPU corrects the detected detection patterns based on the detected quantity of reflection light. One of the image forming conditions is adjusted by the CPU, based on the corrected detection result of the detection patterns. Another one of the image forming conditions is adjusted by the CPU. The detection of the quantity of reflection light from the endless belt is carried out in timing synchronous with the adjustment of the other image forming condition.

摘要:
There is provided an image forming apparatus of the type that a toner image, which is transferred onto an intermediate transfer member, onto a sheet material, is transferred onto a sheet material, which is capable of reducing the possibility of leading end misalignment even if there is a delay in conveyance of the sheet material. An image forming device forms an image on a photosensitive member. An image carrier carries an image. A first transfer device transfers the image carried by the image carrier onto a sheet. A second transfer device transfers the image transferred onto the image carrier onto a sheet. A feeding device feeds the sheet. A conveying device conveys the sheet fed by the feeding device to the second transfer device. A controller controls the conveying device to cause the sheet to be temporarily stopped at a first location and a second location between the feeding device and the second transfer device. The controller is operable when determining that, if the sheet is caused to be temporarily stopped at the first location, the sheet cannot be conveyed to the second transfer device by the conveying device in time for timing in which the image carried by the image carrier reaches the second transfer device, for providing control to inhibit the sheet from being temporarily stopped at the first location.

摘要:
A color image forming apparatus including image forming portions for respective color components of yellow, magenta, cyan, and black. It can be set whether a discriminating function of discriminating whether an original image is a color image or a monochromatic image is used. If the use of the discriminating function is set, a preparatory operation of forming the image in a full-color recording mode is performed before obtaining a result of the discrimination. When the result of the discrimination is monochrome, the image formation in a monochrome recording mode is executed after a shift from the full-color recording mode to the monochrome recording mode. If configured to perform the preparatory operation of forming the image in the monochrome recording mode before obtaining the result of the discrimination, when the result of the discrimination is color, the image formation in the full-color recording mode is executed after a shift from the monochrome recording mode to the full-color recording mode.
