Abstract: An image forming apparatus includes a transfer roller that can be separated from an intermediate transfer belt. When an operational mode is switched from a multicolor mode to a mono-color mode, the image forming apparatus changes a rotational speed of the intermediate transfer belt to a level slower than a rotational speed of the intermediate transfer belt to be set in the multicolor mode to transfer a toner image to the intermediate transfer belt, then separates a first transfer member from the intermediate transfer belt, and after the first transfer member is separated from the intermediate transfer belt, the image forming apparatus increases the rotational speed of the intermediate transfer belt to a rotational speed to be set in the mono-color mode to transfer the toner image to the intermediate transfer belt.

Abstract: There is provided an image forming apparatus that accurately obtains the dynamic characteristic of the apparatus when a foreign substance is adhered to a driving roller for driving an endless belt, such as a facing roller. To accomplish this, the image forming apparatus uses an optical sensor to detect information of a foreign substance on the facing roller. When it is determined that there is no foreign substance information, the image forming apparatus executes profile detection of an intermediate transfer belt using the nominal circumference of the facing roller. When the optical sensor detects foreign substance information, the image forming apparatus measures the circumference of the facing roller, and performs profile detection of the intermediate transfer belt using the measured circumference of the facing roller.

Abstract: The image forming apparatus calculates a total length of a blank region in which toner is not moved with respect to the length of the recording material in a direction perpendicular to the direction of conveying the recording material P. When the toner image on the intermediate transfer belt is transferred to the recording material P in the secondary transfer unit and the total length of the blank region without the toner image is greater than a preset first reference value, a voltage supplied to a secondary transfer roller is corrected such that the voltage has the same polarity as the preset reference voltage according to the first reference value and the absolute value is greater than the absolute value of the reference voltage.

Abstract: An image forming apparatus is provided that includes a detection unit to detect a measure of consumption of a second cartridge. A difference between toner amounts is acquired by subtracting a toner amount per unit area of a toner image corresponding to a maximum density image formed on a first image bearing member from a toner amount per unit area of a toner image corresponding to a maximum density image formed on a second image bearing member. When the detection unit detects a second measure of consumption that is in a consumed state more than a first measure of consumption, a control unit controls a first toner forming unit and a second toner forming unit so that a difference between toner amounts is greater than when the detection unit detects the first measure of consumption.

Abstract: There is provided an image forming apparatus which shortens the time taken for circumference detection and measures the circumference at high precision without obstructing downsizing of the apparatus. To accomplish this, the image forming apparatus detects, at an arbitrary timing, the physical pattern of the image-formed surface of a rotation member that changes over time. In the second round, the image forming apparatus detects the second pattern at a timing a predetermined time after the arbitrary timing. By using the detected patterns, the image forming apparatus obtains information associated with the circumference of the rotation member.
