摘要： An image forming apparatus is configured to execute a first image forming mode, in which an image is formed by forming toner images on a first photosensitive member and a second photosensitive member, and a second image forming mode, in which an image is formed by releasing the first photosensitive member from an outer peripheral surface of an intermediate transfer member and bringing the second photosensitive member into abutment against the outer peripheral surface of the intermediate transfer member. A control unit is configured to set a potential difference, which is a difference between an absolute value of a dark point potential of the second photosensitive member and an absolute value of a direct current component of a developing bias, to be smaller in a case of a second image forming mode than in a case of a first image forming mode.

摘要： An image forming apparatus includes a polygon mirror having a first mirror surface and a controller. The controller is configured to: acquire a detection interval corresponding to one rotation of a polygon mirror; start scanning exposure with a first beam deflected by the first mirror surface, in response to elapse of a first time period after a detection signal has been detected; and start scanning exposure with a second beam deflected by the first mirror surface, in response to elapse of a second time period after the detection signal has been detected. The second time period is calculated based on the detection interval.

摘要： An image forming apparatus that is capable of determining whether a measurement image is formed normally. First and second image forming units form first and second images on an image bearing member using first and second color toners. Reflectance of first toner is higher than the image bearing member and is higher than the second toner. A controller controls image forming units to form first and second measurement images superimposed. A correction unit corrects a positional relationship between the first and second images based on a position of the first measurement image detected based on an output timing of a signal indicating that the received light amount is not less than a threshold. A prohibition unit prohibits the correction unit from correcting the positional relationship when a period during which the signal is output is different from a predetermined period.

摘要： An image forming apparatus includes image carriers for four fundamental colors of black, cyan, magenta, and yellow, and for an auxiliary color, and three optical scanning devices. A first optical scanning device includes two light sources for the black color and another fundamental color, a first deflector, and a first housing. A second optical scanning device includes two light sources for other two fundamental colors, a second deflector, and a second housing. A third optical scanning device includes a light source for the auxiliary color, a third deflector, a third housing, and one or more reflecting mirrors. The light source for the auxiliary color is disposed closer to the third deflector with the one or more reflecting mirrors to turn an optical path therebetween while maintaining an optical path length thereof. The optical paths for the auxiliary color and for the black color have identical light utilization efficiency.
