摘要： A toner developing quantity detection unit operates a plurality of electrostatic recording units to transfer Y, M, C and K color component toner marks onto a belt. A toner developing quantity correction unit detects toner developing quantities per unit area of color toners on the basis of detection signals of the color component toner marks on the belt optically detected by a sensor. The toner developing quantity correction unit corrects the toner developing quantities so as to allow the toner consuming quantities of the plurality of electrostatic recording units to be substantially the same level, on the basis of the thus detected toner developing quantities.

摘要： An image-forming device such as a full color printer is provided which is designed to correct the speed of a conveyer belt on which print sheets are transported or intervals between image-transferring units for compensating for a shift between colors. The image-forming device has a timer which measures an elapsed time from turning on of the device or release of a sleep mode, a print-off time and a print time and determines a correction value as a function of the times measured by the timer by look-up using a table.

摘要： In a recording device, electrostatic recording units of Y, M, C and K are arranged along the direction of the feed of a recording sheet by a belt unit. The device forms latent images corresponding to image data by optical scanning of an exposure device onto a rotating photosensitive drum, develops the latent images with toner components having different colors, and then transfers the developed images onto the recording sheet on the belt unit. A color matching processing unit performs color matching processing including color slippage correction of different color images. An automatic color matching mode processing unit works the color matching processing unit when conditions beforehand decided in the state that an automatic correction mode is set up are realized. A manual color matching mode processing unit controls the color matching processing unit when the manual color matching mode processing unit recognizes operator's manual color matching instructing operation in the state that a non-correction mode is set up.

摘要： The ratio detecting unit detects, upon stoppage of printing, a fixing control ratio K which represents a ratio of time during which the fixing unit was controlled to the printing temperature in a certain period of time in the past. The predicting unit predicts a fan driving time Tf after stoppage of printing in response to the thus detected fixing control ratio K. The fan control unit rotation-controls the cooling fan 42 during printing, keeps the fan controlling status for printing for a fan driving time Tf upon stoppage of printing, and upon lapse of the fan driving time Tf, fan stoppage or high-speed rotation is switched over to low-speed rotation.
