摘要： Disclosed is an image forming apparatus, which makes it possible to reduce the frequency of image defect occurrences to a level as lower as possible by detecting abnormalities generated with age on the photoreceptor member and/or in the cleaning section, so as to suppress an amount of spoiled paper sheets and material. The image forming apparatus includes: a light source that is disposed at a position located between a cleaning section and a charging section, to emit an inspection light, which is to be irradiated onto a photoreceptor member over a main-scanning direction thereof; a tight-contact type image sensor that has a line image sensor to receive the inspection light reflected from a surface of the photoreceptor member; and a control section to determine a status of a surface of the photoreceptor member, based on a result of analyzing the inspection light receive by the line image sensor.

摘要： When conveying an envelope, a posture of the envelope is corrected by hitting a closed portion of the envelope, which is opposite side of an opened portion of the envelope, against a nip portion between upper and lower rollers of the pre-registration rollers and the envelope is then conveyed with the envelope being nipped by the upper and lower rollers of the pre-registration rollers. The upper and lower rollers of the pre-registration rollers nip the envelope to remove air from the envelope. When setting an envelope mode to control a conveying speed of the envelope based on a coverage rate of an image to be formed on the envelope, the conveying speed of the envelope is controlled by adjusting a rotation speed of the registration rollers based on the coverage rate of the set envelope mode.
