摘要： An image forming apparatus includes an image bearing member for carrying a toner image; an image forming unit for forming a toner image on the image bearing member; a transfer material carrying member, for carrying a transfer material, wherein the toner image is transferred onto a transfer material carried on the transfer material carrying member or onto the transfer material carrying member; a density detecting unit for detecting a density of the toner image transferred to the transfer material carrying member; wherein a transfer intensity is smaller when the toner image for density detection is transferred onto the transfer material carrying member than when the toner image is transferred onto the transfer material carried on the transfer material carrying member.

摘要： An image forming apparatus includes an image bearing member for carrying a toner image; an image forming unit for forming a toner test image on the image bearing member; a transfer material carrying member, for carrying a transfer material, wherein the test toner image is transferred onto a transfer material carried on the transfer material carrying member or onto the transfer material carrying member; and a density detecting unit for detecting a density of the toner test image transferred to the transfer material carrying member. A transfer intensity is smaller when the toner test image for density detection is transferred onto the transfer material carrying member than when the toner test image is transferred onto the transfer material tarried an the transfer material carrying member. The transfer intensity also changes depending on whether the transferred toner test image is the first color toner test image or the second toner test image, and depending on an ambient condition sensor.

摘要： An image forming apparatus has an image bearing member bearing images thereon and movable, and a transfer medium bearing member provided in pressure contact with the image bearing member and bearing a transfer medium thereon and rotatable. The transfer medium bearing member has a sheet member for bearing the transfer medium thereon, and an elastic layer supporting that area of the sheet member bearing the transfer medium thereon from the inside of the sheet member. A voltage is applied to the transfer medium bearing member to transfer the images on the image bearing member to the transfer medium born on the sheet member. The sheet member has an area not fixed to the elastic layer. The transfer medium bearing member is rotated with a potential difference created between the image bearing member and the sheet member before the operation of transferring the images on the image bearing member to the transfer medium born on the sheet member is started.
