摘要： An image forming apparatus includes an image bearing body, a latent image forming section that forms a latent image on the image bearing body, a development section that develops the latent image using toner, a transfer section that transfers a toner image to a transferred body, a pressuring and contacting section that pressures and contact the transfer section against and with the image bearing body via the transferred body, a cleaning blade that removes residual toner, and a controller. The controller analyzes a print pattern of the image to be formed on the sheet. The controller controls the pressuring and contacting section to change a contact state between the image bearing body and the transferred body while adjusting an image patch formed in a domain corresponding to an inter-sheet portion between the sheet and the next sheet on the image bearing body according to an analysis result.

摘要： A developing device of an electrophotographic image forming apparatus has a first roller and a second roller disposed in a peripheral contact with the first roller to define a contact region therebetween so that the first roller is capable of supplying and collecting a toner to and from the second roller in the contact region. The first roller has a core and a polyurethane foam layer. The polyurethane foam has an open ratio of cells of 2% or more and 50% or less and a hardness of 1 gf/mm or more and 6 gf/mm or less, the hardness being defined by a load per unit length in a longitudinal direction of the first roller, the load being determined by forcing the peripheral surface of the polyurethane foam layer against a substrate, measuring a load necessary for the polyurethane foam layer to be compressed by 30% in thickness, and dividing the load by a length of the polyurethane foam layer in the longitudinal direction. The first and second rollers are disposed so that the contact region has a peripheral width of 3 mm or more and 8 mm or less.
