An image forming apparatus comprises: an image forming unit to form an image onto a recording medium; a measuring unit to measure a density of the image formed on the recording medium; a controller to execute an image stabilizing control to decide image forming conditions of the image forming unit on the basis of the image density measured by the measuring unit; a heater to heat a load by supplying a current to the image forming apparatus; and a detector to detect a temperature of the load which is heated by the heater, wherein the controller controls the execution of the image stabilizing control in accordance with an output of the detector at the start of the power supply to the apparatus. When the detected temperature of the load is less than a predetermined value, the image stabilizing control is executed. When it is equal to or higher than the predetermined value, the image stabilizing control is not performed. When the image stabilizing control is executed, the control means allows the image forming unit to form a sample image and the image forming conditions are controlled on the basis of the state of the sample image.

An image forming apparatus includes an image forming unit for forming an image on a recording medium, and a measurement unit which measures the density of the image formed on the recording medium. A control unit determines an operation condition of the image forming unit on the basis of the measurement result from the measurement unit. A storage unit stores the operation condition determined by the control unit, and a display unit reads out the operation condition at a predetermined time for display. The control means controls a subsequent operation of the image forming apparatus according to the stored operation condition.

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.

摘要:
An image heating apparatus has a heater for generating heat by energization, a heat member heated by the heater, a temperature detector for detecting a temperature of the heat member, and an energization control for controlling the energization of the heater in such a manner that the temperature detected by the temperature detector is maintained at a target temperature. When the temperature of the heat member is detected to reach a lowermost point during a contiuous copy operation, the energization control reduces power.

An image forming apparatus for forming an image on a recording member includes an unfixed image forming device for forming an unfixed image on the recording member, a fixing section which has a nip, and which holds and conveys the recording member carrying the unfixed image through the nip to fix the unfixed image on the recording member, and a conveyor for conveying the recording member to the fixing section. The conveyor can convey the recording member at a first speed, or at a second speed which is slower than the first speed. The conveyor conveys the recording member at the first speed before a leading end of the recording member is held by the nip, and at the second speed after the leading end is held by the nip. With such a construction, the recording member can be forcibly inserted into the nip, and can be prevented from slipping at the entrance of the nip.

A fixing apparatus includes a rotary member for thermally fixing a nonfixed image to a recording material, and a mold releasing agent applying device for applying a mold releasing agent to the rotary member. The mold releasing agent applying device has a regulating member contacted with the rotary member to regulate an amount of the mold releasing agent supplied to the rotary member. A holding member is disposed at an upstream side of the regulating member in a rotating direction of the rotary member and is adapted to hold the mold releasing agent. A supplying member supplies the mold releasing agent to the holding member, wherein a supplying timing of the mold releasing agent supplied from the supplying member to the holding member is effected periodically after a plurality of fixing process operations.
摘要:
An image forming apparatus includes an unfixed-image forming unit for forming an unfixed image having a plurality of colors on a recording material, and a fixing unit for fixing the unfixed image formed by the unfixed-image forming unit by heating the recording material bearing the image. The fixing unit can fix the unfixed image on the recording material with a first degree of fixing or with a second degree of fixing which is greater than the first degree of fixing depending on whether or not a light-transmitting-property recognition unit recognizes the recording material to have a light-transmitting property, and whether or not a black-monocolor recognition unit recognizes the unfixed image formed by the unfixed-image forming unit as a black monochromatic image. When the image forming apparatus recognizes that the recording material has a light-transmitting property and that the unfixed image is a black monochromatic image, the fixing unit can fix the unfixed image with the first degree of fixing or with the second degree of fixing based on information relating to an image formed by the fixing unit.
