摘要： An image forming apparatus, employs a constitution in which, in a case that a relative position between an inner roller and an outer member with respect to a circumferential direction of the inner roller is changed in a period after a preceding recording material passed through a transfer portion and until a recording material subsequent to the preceding recording material reaches the transfer portion during execution of a job for forming and outputting images on a plurality of recording materials, a controller controls a position changing mechanism so that the relative position between the inner roller and the outer member is changed in a state in which the outer member contacts an intermediary transfer belt.

摘要： An image forming apparatus includes a first sensor configured to measure measurement images on a first photoreceptor, a second sensor configured to measure measurement images on an intermediate transfer member, and a controller. The controller controls a first image forming unit to form first measurement images, wherein the first measurement images are formed along a rotation direction of the first photoreceptor, and controls the first sensor to measure the first measurement images on the first photoreceptor. The controller further controls the first image forming unit and a second image forming unit to form a plurality of measurement images while a rotation speed of the first photoreceptor is being controlled based on a measurement result of the first sensor, wherein the plurality of measurement images are formed along the predetermined direction of the intermediate transfer member.

摘要： An image forming apparatus is configured to calculate an estimated value of a color misregistration amount based on a first estimation expression when a temperature of an exposure device is under a temperature increasing state. The image forming apparatus is configured to calculate the estimated value of the color misregistration amount based on the first estimation expression when the temperature of the exposure device is under the temperature decreasing state and the exposure device is not in a thermally-deformed state. The image forming apparatus is configured to calculate the estimated value of the color misregistration amount based on a second estimation expression when the temperature of the exposure device is in the temperature decreasing state and the exposure device is in the thermally-deformed state. The image forming apparatus is configured to correct color misregistration based on the calculated estimated value.

摘要： Prediction accuracy of a color misregistration amount in an image formation executed in an image forming apparatus is improved. The image forming apparatus comprises an optical box storing an optical system for irradiating a laser beam from a laser source to a photosensitive drum, a scanner temperature sensor provided near the optical box, and an environmental temperature sensor for detecting a surrounding temperature of the image forming apparatus, and a control section. When image formation is executed, the control section obtains a temperature Tscn detected by the scanner temperature sensor and a temperature Tenv detected by the environmental temperature sensor and calculates a prediction value of a position misregistration amount to the photoreceptor of the laser beam using the difference between Tscn and Tenv.
