摘要： An image forming apparatus includes an image carrier, a transfer unit, and a control unit. The image carrier has a surface to bear a toner image thereon. The transfer unit has a transfer member to transfer the toner image onto a recording sheet conveyed in a conveyance direction for trailing-end borderless image formation and duplex image formation. The transfer unit is configured to form the toner image on the recording sheet without forming a margin at a trailing end of the recording sheet in the conveyance sheet in the trailing-end borderless image formation. The transfer unit is configured to form the toner image on front and back faces of the recording sheet in the duplex image formation. When a width of the toner image formed in a borderless image area of the recording sheet in the trailing-end borderless image formation is smaller in a direction perpendicular to the conveyance direction than a threshold value, the control unit permits the duplex image formation. When the width is the threshold value or greater, the control unit prohibits the duplex image formation.

摘要： In a RAM are stored a first deflection information table representing the relationship between the rotation amount and the deflection amount of a photosensitive element, a second deflection information table representing the relationship between the rotation amount and the deflection amount of a developing sleeve, a writing sensitivity information table representing the relationship between the rotation amount of the photosensitive element and latent image writing sensitivity, and an image forming condition information table representing the relationship between the rotation amount and laser power. An information input unit is provided to input the respective tables. During a print job, laser power is changed on the basis of the image forming condition information table, and laser power which causes deviation in an opposing direction is calculated on the basis of information input in a standby state to update the image forming condition information table.
