摘要： An image forming apparatus is disclosed which has at least a first image forming unit provided with a first latent image-holding member, a first latent image-forming means, a first developing means for developing a first latent image with a first toner to form a first toner image, and a first image-transfer means for transferring the first toner image to an image-receiving member, and a second image-forming unit provided with a second latent image-holding member, a second latent image-forming means, a second developing means for developing a second latent image with a second toner to form a second toner image, and a second image-transfer means for transferring the second toner image to the image-receiving member holding the first toner image. The second developing means also serves as a cleaning means for recovering the toner remaing on the second latent image-holding member after the transfer to perform cleaning. The second latent image-holding member has a surface having a contact angle for water of not less than 85 DEG .

摘要： An image forming apparatus wherein a laser beam produced by a laser source is imaged through an imaging optical system on an image bearing member as a beam spot. The beam spot scans the image bearing member in a main scan direction. The laser source is rendered on and off to form an image with picture elements. The laser driving pulse width per picture element is changed in accordance with the image density of the image to be formed, so that the tone gradation of the image is provided on the image bearing member in accordance with the pulse width. The size of the spot measured in the main scan direction (1/e2 diameter) is not more than 0.7 times of the size of the picture element measured in the main scan direction.
