Patent ID: 8019243

Claim:
An image forming apparatus, comprising: a photosensitive member which has a rotatable surface; image forming means which forms an image on the photosensitive member; a time information obtaining device which obtains information about a rotation time and information about a stop time, the rotation time being a period of time elapsed from a time when the photosensitive member in a stop state starts rotating, the stop time being a period of time elapsed from a time when the photosensitive member in a rotation state stops rotating; a temperature and humidity detecting device which detects information about a temperature and humidity of the image forming apparatus; a fixing device which fixes a toner image transferred to a recording material; and a controlling device which controls an image forming condition of the image forming means, the controlling device determining the image forming condition for a subsequent image formation based on the information about the rotation time, the information about the stop time, the information about the temperature and humidity, and whether an image formation that precedes the subsequent image formation is performed in a first print mode or a second print mode, wherein the first print mode is a mode in which a recording material that has passed through the fixing device does not pass through a position in which the toner image is transferred to the recording medium, and the second print mode is a mode in which a recording material that has passed through the fixing device is allowed to pass through the position in which the toner image is transferred to the recording medium.
