摘要： An electrostatic image forming apparatus has an image bearing member, a movable recording material carrying member and a transfer unit for effecting electrostatic transfer of an image from the image bearing member onto a recording material being carried. A control is provided for controlling start timing of a change of a transfer output of the transferring mechanism in accordance with the humidity so that the output reaches a level effective to transfer the image. The control controls the start timing from before a leading edge of the recording material carried on a movable recording material carrying member reaches a transfer position until a leading edge of an image formation area of the recording material reaches that transfer position.

摘要： An image forming apparatus has an image bearing member, a movable recording material carrying member, transferring means for transferring the image from image bearing member to the carrying member and a fixing unit. A control starts timing of application of a transfer output of the transfer means so that the output reaches a level effective to transfer the image before a leading edge of an image formation area of the recording material reaches the transfer position and the transfer means is effective to transfer the image on a second side of the recording material with a transfer output that is higher than that which was used to transfer the image onto the first side of the recording material. Start timing of application of transfer output of the transfer means is done so that application of the transfer output onto the first side is started after the leading edge of the recording material passes through the transfer position and before the leading edge of the image formation area reaches the transfer position and so that a time period from the start of application of the transfer output for the transfer operation onto the second side to arrival of the leading edge of the image formation area at the transfer position is longer than a time period from the start of application of transfer output for a transfer operation onto the first side to arrival of the leading edge of the image formation area of the transfer position.

摘要： In an image forming apparatus, residual toner on an image bearing body is prevented from falling on a convey belt which conveys a recording medium. The convey belt is shifted in a direction perpendicular to a convey direction in which the recording medium is conveyed. A cleaning blade for removing residual toner from the image bearing body has a width that is larger than the range in which the convey belt is movable in the direction perpendicular to the convey direction. No cleaning device is required for the convey belt.

摘要： In a multi-image forming apparatus having a plurality of electrophotographic photosensitive members and adapted to form a multi-image by sequentially transferring image formed on the photosensitive drums onto a transfer sheet, it is possible to the service life of the photosensitive member having the higher frequency in use. To this end, the photosensitive member having the higher frequency in use has a different construction which differs from those of the other photosensitive members. Further, if necessary, an image forming method by the photosensitive member having such different construction is differentiated from those by the other photosensitive members.
